Quartet for a few listeners (8)

I believe the answer is:

foursome

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

'quartet for a few listeners' is the definition.
I can't judge whether this definition defines the answer.

'quartet for a few' is the wordplay.
'quartet' becomes 'four' (synonyms).
'for' means one lot of letters go next to another.
'a few' becomes 'some' (both can mean a small amount of something).
'four'+'some'='FOURSOME'

Can you help me to learn more?

(Other definitions for foursome that I've seen before include "enough for rubber" , "Golfing group, perhaps" , "The Beatles, for example" , "In game" , "golf match" .)
