My apologies, Carrie, if I misunderstood. My recollection was that you had stated on this board, at least a couple of times in the past, that David was no longer interested performing on stage with Mike, apparently due to something Mike had said or done at some point in time. After reading that, I also remember thinking that Mike, often in an attempt at humor, has a history of making sardonic comments, and that perhaps David had taken one of those comments more in a serious way that Mike may have intended. (And Mike himself is sometimes the target of his acerbic wit.)
Anyway, those must not have been your most recent statements on David touring as a Beach Boy, and I'm glad to hear that he's interested and hope that there will a number of BB 50th anniversary reunion activities.
That's OK, its just that sitting in with Mike's band when they are on the east coast purely for the social aspect and being part of an official reunion event that includes all the surviving Beach Boys are two different things, and he very much wants to be part of any 50th celebrations that may occur.
Now as far as his personal relationship with Mike goes, just yesterday I dropped David off for a flight to LA and as he was leaving he said "I wish I was leaving to go on the road with Mike's band instead" so he must be over it. Absence makes the heart grow fonder, I guess.
