I'm a little stuck... Click here to teach me more about this clue!

'drummer' is the definition.
(I know this)

I cannot understand how the rest of the clue works.

(Other definitions for starr that I've seen before include "Ringo --, drummer" , "Freddie . . . . . Ate My Hamster" , "Beatle Ringo" , "rush up north" , "English rock star and drummer, b. 1940" .)

I've seen this clue in The Sun.
