In articles about how they met, I remember reading something to the effect of Sheila "working with him on the PR soundtrack."

We know she is not credited on the soundtrack album (nor do I hear anyhting to suggest she's on there).

But there's a lot of incidental music in PR which has lots of percussion, drum effects etc.

Is there any official source or knowledge that she did workon that? My gut says she did but curious what anyone else might know.
