I'm typesetting some poetry that needs to be numbered but that is frequently interrupted by comments, something like a play. I want the numbering to be continuous from verse to verse but to omit the lines of comments, like the drama packages have. I also want to be able to restart the line number occasionally. How would I go about this?

\begin{verse}
O'er every birth a star of fate presides,\\
And he that knows his orb of destiny,\\
May, by the changes of its radiance, tell\\
Whene'er his good or evil genius reigns.\\
This knowledge, earned by many a midnight vigil,\\
Has taught me that yon silver star is mine,\\
Which nightly, since I conn'd this wond'rous volume,\\
Hath dimm'd its fires, and warn'd me to forbear.\\
Yet have I still undaunted read, and now,\\
While pale and fitfully its beams shrink in,\\
The ingredients of a potent spell I mingle,\\
And but three drops of my own blood are wanting,\\
To give me proof that to my hests and bidding,\\
A spirit of dread ministry will come.\\
Why should the glorious planet fade at this?\\
Is there then peril to my better part\\
In this mysterious science? If I stop,\\
How shall I know the secrets written here\\
Are knowledge or phantasma? Can there be\\
Evil in truth? For to unfold the art\\
That summons spirits from their dark abode,\\
Is but to know what is -- and what the gods,\\
In their eternal mysteries have framed. -- \\
Shrink into darkness thou faint trembling light,\\
I will abide the issues of the spell.\\!
\end{verse}
Commentary Section 1
\begin{verse}
The blood refuses. Why will it not come?\\
It was no groan! `Tis but the sighing wind,\\
That sweeps along the silent galleries.\\
What coward palsy am I smitten with?\\
I'll strike again. It flows -- so now `tis done.\\
What a horrible apocalypse is this?\\
``If thou on All Soul's Eve wilt be but mine,\\
To all thy wishes I will be thy slave.'' --\\
Who and what art thou? Show me first thy face, --\\
The strong condition of thy proffer'd service.\\!
\end{verse}
