Maturer blokes somehow becoming rabble-rousers (13)

I believe the answer is:

troublemakers

'rabble-rousers' is the definition.

'maturer blokes somehow' is the wordplay.
'somehow' indicates an anagram.
'maturer'+'blokes'='maturerblokes'
'maturerblokes' is an anagram of 'TROUBLEMAKERS'.

'becoming' is the link.

I've seen this clue in The Times.
