How many 1960-1970's bands are there whose original members are still alive

Just for the record, neither the Stones nor the Beatles even made it out of the sixties without a dead original member.

See Stu Sutcliffe and Brian Jones.

Yes, Yes! (knocking wood)

I can attest that Rush is indeed still around. I just saw them do two shows this weekend.

Last I heard, their original drummer, John Rutsey, is still alive and doing well in Toronto.
