Beatle drummer (5)
I believe the answer is:
starr
'beatle drummer' 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 "Beatle Ringo" , "English rock star and drummer, b. 1940" , "Ringo - (The Beatles)" , "rush up north" , "Freddie . . . . . Ate My Hamster" .)
