One could have groupies excluded from audition (4)
I believe the answer is:
band
'audition' is the definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.
'one could have groupies excluded' is the wordplay.
I cannot quite understand how this works, but
'one' could be 'an' (an apple is one apple) and 'an' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
'from' is the link.
Can you help me to learn more?
(Other definitions for band that I've seen before include "Orchestra" , "See 23" , "Capital of Tibet" , "troop" , "Outline drawing" .)
