The Wailers didn't become "Bob Marley and The Wailers" until the album after "I Shot The Sheriff" appeared on. Peter Tosh and Bunny Wailer left the trio and Bob got a backing band and kept the Wailers name. Bob was the front man of the Wailing Wailers vocal trio for years.
As far as I know, Bunny is the only one left alive. Peter and Bob died young. Peter was murdered in Jamaica, and Bob, of course, died of cancer. I don't think either of them made 40?
