Another one that just barely misses the 60's start date (formed 1970) the 5 guys that recorded the first Aerosmith album are today the 5 guys in the band 40+ years later. Yes, they did have a different 2nd guitarist before Brad Whitford joined in 1971 and Joe & Brad did leave from 79-84 but other than that, it's been the same five guys surviving each other for the majority of the time.
