Fan urging Queen to be more like Nirvana? (8)

I believe the answer is:

grungier

'be more like nirvana?' is the definition.
(Nirvana are a grunge band)

'fan urging queen' is the wordplay.
'fan' indicates an anagram (letters must be fanned around).
'queen' becomes 'ER' (abbreviation for Elizabeth Regina).
'urging' with letters rearranged gives 'grungi'.
'grungi'+'er'='GRUNGIER'

'to' is the link.

I've seen this clue in The Independent.
