If Christine in the Guardian said: "I loved the stuff we did with Bob Welch [in the early 70s]: Mystery To Me, Bare Trees, Future Games" why would she be the person keeping Bob from the R&R Hall? Or is it a clever ruse? I don't know anymore... I think part of it is that with so many members the line gets drawn someplace, but Bob was a major part.
Christine also makes a comment that leaves the impression Sandy Denny only sang, but she was a fantastic pianist and a very good acoustic guitarist too. Maybe she had her confused with Lulu or something?
