re: Joe Pesci -- Sorry I can't footnote this interesting little sidelight; I've heard and/or read it more than once, via talk shows, magazines, etc., enough to satisfy myself that it's probably true.

First time I heard it, I thought he might be one of the voices heard on the various hits, but later got clarification that he joined later, after Frankie Valli had split to go solo. Didn't participate in any hit records, just sang live on the oldies-show circuit or whatever.

Both Joe and the group are from New Jersey -- that much can be documented. I realize that this is only vague circumstantial evidence, but it might serve to make the story a bit more believable.

SINSULL: IF you aren't dealing with mics or anything similar, how do you sing together? Just uses yall''s immaginations?
