Bugle players leave hindquarters in Queer Street (10)
I believe the answer is:
trumpeters
'bugle players' is the definition.
'trumpeters' can be an answer for 'players' (trumpeter is a kind of player). I am not sure about the 'bugle' bit.
'hindquarters in queer street' is the wordplay.
'hindquarters' becomes 'rump' (synonyms).
'in' is an insertion indicator.
'queer' indicates an anagram.
'street' anagrammed gives 'teters'.
'rump' placed inside 'teters' is 'TRUMPETERS'.
'leave' is the link.
Can you help me to learn more?
(Another definition for trumpeters that I've seen is " musicians".)
