No, didn't dream it! I found this at Amazon.
"Great movie, but they cut a scene on the DVD. It's only about a minute, but the scene which features BABY YOUR A RICH MAN is cut. They played about a minute of this song as the boys revived the pepper band. If you can find an old copy of the VHS (the one in a box, NOT in a case) you can find this scene on it. Oddly, RICH MAN is on the new CD "songtrack", yet it's now cut from the film. I hope they issue a complete uncut version someday."
Thankfully someone else remembered it! I knew I wasn't crazy! I had taped the movie when I was little (audio taped! the time before VCR's!) So I knew something was off when I watched the DVD. Oh, and the Hey Bulldog was never there before, but it's okay.
