Ramones upset crew (7)
I believe the answer is:
oarsmen
'crew' is the definition.
(I've seen this before)
'ramones upset' is the wordplay.
'upset' indicates an anagram.
'ramones' is an anagram of 'OARSMEN'.
(Other definitions for oarsmen that I've seen before include "They row the boat" , "Crew - moaners (anag)" , "Male rowers" , "Rowing types" , "Scullers" .)
