U2 singer around grand drum (5)
I believe the answer is:
bongo
'drum' is the definition.
(I know that bongo is a type of drum)
'u2 singer around grand' is the wordplay.
'u2 singer' becomes 'Bono' (I've seen this in another clue).
'around' indicates putting letters inside.
'grand' becomes 'G' (G is short for ground as in a thousand).
'bono' enclosing 'g' is 'BONGO'.
(Other definitions for bongo that I've seen before include "One beaten" , "Hand drum" , "Throw; stopper" , "Small drum; antelope" , "Bucket-shaped drum - rare spiral-horned antelope" .)
