As we know John Juke Logan plays the opening music and all the little scene segues on Roseanne. John Popper appeared in a recent episode as an old band friend of Dan's coming back for a gig in his home town after making good. What does this have to do with the segues and opening? In the show that was mentioned (a rerun btw) Mr. Logan's music was still very much present. John Popper enjoys much popularity and currently tours to full houses at large venues. Why would he drop what must be a very profitable career to play backing music for a tv sitcom? I don't think so. It would seem obvious that Mr. Popper's recent appearance would seem to be a cameo and nothing more. fjm
