I think you would be interested to see this documentary from the Biography channel which not only interviewed Bob Welch, but also half-forgotten members Rick Vito, Billy Burnette, and Bekka Bramlett. Only problem is whoever made this documentary clearly didn't bother with music clearances and it's almost all generic ("Oh Well" somehow made the cut). There's nothing worse than a music documentary that omits the music but it's cool to hear from the usually unsung band members.

EDIT: It also claims that Bekka Bramlett and Dave Mason were introduced at the Clinton inauguration performance. Umm what?
