Ringo of the Beatles (5)
I believe the answer is:
starr
'ringo of the beatles' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for starr that I've seen before include "Ringo - (The Beatles)" , "Freddie . . . . . Ate My Hamster" , "English rock star and drummer, b. 1940" , "Ringo --, drummer" , "Beatle Ringo" .)
