I am editing a conference proceedings volume for Springer. Springer provides a bibliography style file (spbasic.bst), but several authors have used the natbib package in their source in order to be able to use \citet.
However, the use of natbib seems to override the bibliography style. As such these papers end up having a bibliography style that is inconsistent with the rest of the papers in the volume.
Is there a way to make natbib play nicely with spbasic.bst?
