Players, presumably all-rounders (4)
I believe the answer is:
band
'players' is the definition.
(group playing music)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for band that I've seen before include "Loop; rock group" , "Pop group, perhaps" , "See 23" , "Capital of Tibet" , "Zone; group" .)
