Move names of editors followed by (Ed./Eds.) and a comma before title in biblatex

Question

For a stylesheet I am following, I need to move the names of the editors of a book before the book title. In biblatex, the default behavior is to print Ed. by followed by the names. A similar question has been asked before (Citing @inbook with biblatex: how to put authors/editors before book title?), but the only answer given differs in many respects from what I need, and I don't know how to modify it to suit my needs here.

In the MWE, the printed result is:

Lennon, John (1965). This is my article in this book. In A book with articles. Ed. by Paul McCartney, John Lennon, George Harrison & Richard Starkey. Liverpool: Cavern Club. 65-87.

Whereas I need it to be:

Lennon, John (1965). This is my article in this book. In Paul McCartney, John Lennon, George Harrison & Richard Starkey (Eds.), A book with articles. Liverpool: Cavern Club. 65-87.

Notice the uppercase E in Eds. (which should be Ed. in the case of a single editor) and the comma following it.

\documentclass{article}
\usepackage[style = authoryear-comp, maxnames = 99]{biblatex}

\renewcommand*{\finalnamedelim}{\addspace\&\space} % use '&' before last author in citations and bibliography
\renewcommand*{\intitlepunct}{\space} % remove colon after "In:" for articles in books
\DeclareFieldFormat[article, incollection, unpublished]{pages}{#1} % no word 'pages' for articles in the bibliography (print as is)
\DeclareFieldFormat[article, incollection, unpublished]{title}{#1} % no quotes for article titles (print as is)
\renewcommand{\bibpagespunct}{\ifentrytype{article}{\addcolon}{\addperiod\addspace}} % colon between volume and page ranges for journal articles, period plus space for articles in books

\usepackage{filecontents}
\begin{filecontents}{\jobname.bib}
@incollection{lennon1965,
    AUTHOR = "John Lennon",
    BOOKTITLE = "A book with articles",
    EDITOR = "Paul McCartney and John Lennon and George Harrison and Richard Starkey",
    TITLE = "This is my article in this book",
    YEAR = "1965",
    LOCATION = "Liverpool",

Shameless plug: The styles of the biblatex-ext bundle have a slightly more sophisticated version of this implemented as an option. Load ext-<standardstyle>, e.g. ext-authoryear-comp and set the option innamebeforetitle to true.

\documentclass[british]{article}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{babel}
\usepackage{csquotes}

\usepackage[backend=biber,
  style=ext-authoryear, innamebeforetitle=true]{biblatex}

\DeclareFieldFormat{editortype}{\mkbibparens{#1}}
\DeclareDelimFormat{editortypedelim}{\addspace}

\DeclareFieldAlias{translatortype}{editortype}
\DeclareDelimAlias{translatortypedelim}{editortypedelim}

\addbibresource{biblatex-examples.bib}

\begin{document}
\cite{sigfridsson,gaonkar:in,westfahl:space,vizedom:related}
\printbibliography
\end{document}

This is really where biblatex is not that flexible.

We can use xpatch to patch the drivers for @inbook, @incollection and @inproceedings

\xpatchbibdriver{inbook}
  {\usebibmacro{in:}%
   \usebibmacro{bybookauthor}%
   \newunit\newblock
   \usebibmacro{maintitle+booktitle}%
   \newunit\newblock
   \usebibmacro{byeditor+others}}
  {\usebibmacro{in:}%
   \usebibmacro{bybookauthor}%
   \newunit\newblock
   \usebibmacro{byeditor:in}%
   \newunit\newblock
   \usebibmacro{maintitle+booktitle}%
   \newunit\newblock
   \usebibmacro{byeditor+others}}
  {}{}

\xpatchbibdriver{incollection}
  {\usebibmacro{in:}%
   \usebibmacro{maintitle+booktitle}%
   \newunit\newblock
   \usebibmacro{byeditor+others}}
  {\usebibmacro{in:}%
   \usebibmacro{byeditor:in}%
   \setunit{\labelnamepunct}\newblock
   \usebibmacro{maintitle+booktitle}%
   \newunit\newblock
   \usebibmacro{byeditor}}
  {}{}

\xpatchbibdriver{inproceedings}
  {\usebibmacro{in:}%
   \usebibmacro{maintitle+booktitle}%
   \newunit\newblock
   \usebibmacro{event+venue+date}%
   \newunit\newblock
   \usebibmacro{byeditor+others}}
  {\usebibmacro{in:}%
   \usebibmacro{byeditor:in}%
   \setunit{\labelnamepunct}\newblock
   \usebibmacro{maintitle+booktitle}%
   \newunit\newblock
   \usebibmacro{event+venue+date}%
   \newunit\newblock
   \usebibmacro{byeditor+others}}
  {}{}

We also redefine byeditor:in

\newbibmacro*{byeditor:in}{%
  \ifnameundef{editor}
    {}
    {\printnames[editorin]{editor}%
     \addspace\bibsentence%
     \mkbibparens{\usebibmacro{editorstrg}}%
     \clearname{editor}%
     \printunit{\addcomma\space}}}

and a new name format

\DeclareNameAlias{editorin}{first-last}

Guidos way, or - without another package, but with a lot of more code lines - you can change the bibliography-driver for @incollection from standard.bbx, to display the data in your wanted order; change the byeditor+others-macro from biblatex.def to put parencites around the editor data; and change the editorstrg from biblatex.def to use the capitalized version \bibcpstring instead of \bibstring.

EDIT fixed the issue of multi-volume (with maintitle) and single editor.

A possibility is to abuse the biblatex in: macro to to format and print the information as desired.

\xpatchbibmacro{editorstrg}{\bibstring}{\bibcpstring}{}{}
\xpatchbibmacro{editorstrg}{\bibstring}{\bibcpstring}{}{}

\renewbibmacro*{in:}{
  \ifentrytype{incollection}{%
  \DeclareNameAlias{editor}{first-last}
  \printtext{In}
  \ifnameundef{editor}
    {}
    {\printnames{editor}%
     \addspace 
     \mkbibparens{\usebibmacro{editorstrg}}
     \setunit{\addcomma\addspace}% 
    }%
  \usebibmacro{maintitle+booktitle}
  \clearfield{maintitle}
  \clearfield{booktitle}
  \clearfield{volume}
  \clearfield{part}
  \clearname{editor}
  }
  {}%
}

In this case the "simple" in: contains the directives to print the editors and the book title.

The tricks are: (1) use a guard, \ifentrytype{incollection}, to restrict the modification to the specific entrytype; (2) delete the content of the fields booktitle and editor, thus they are no longer a available in the rest of directive in the driver for incollection, and (3) define a new directive to switch last name and first name for the editors: this can be specifying that editor is an "alias" for the predefined name format first-last, i.e., \DeclareNameAlias{editor}{first-last}.

Notice that the excellent and convenient xpatch package (i.e., include \usepackage{xpatch}) is used to modify how the biblatex string editor(s) is printed. Notice that we need to patch it twice one: the first for the plural version, and the second for the singular case (only one editor).

Here is the outcome:
