Call round for the one with the sticks (5)
I believe the answer is:
ringo
'the one with the sticks' is the definition.
(Ringo Starr uses drumsticks)
'call round' is the wordplay.
'call' becomes 'ring' (telephone call).
'round' becomes 'o' (round can mean a round object).
'ring'+'o'='RINGO'
'for' is the link.
(Other definitions for ringo that I've seen before include "Beatles drummer" , "Beatle Starr" , "One of The Beatles" , "The familiar Beatle drummer" , "Member of group" .)
