Stop men having to croon backing? (9)

I believe the answer is:

endorsing

'backing?' is the definition.
('endorse' can be a synonym of 'back')

'stop men having to croon' is the wordplay.
'stop' becomes 'end' ('end' can be a synonym of 'stop'**).
'men' becomes 'or' (I've seen this in other clues).
'having' is a charade indicator (letters next to each other).
'to croon' becomes 'sing' (I've seen this before).
'end'+'or'+'sing'='ENDORSING'

(Another definition for endorsing that I've seen is " backing".)

I've seen this clue in The Telegraph.
