Dance for lunatic ex-president (7)

I believe the answer is:

nutbush

I'm a little stuck... Click here to teach me more about this clue!

'dance' is the definition.
I don't know anything about this answer so I can't tell whether this works.

'lunatic ex-president' is the wordplay.
'lunatic' becomes 'nut' (I've seen this before).
'ex-president' becomes 'Bush' (either of the George Bushes).
'nut'+'bush'='NUTBUSH'

'for' acts as a link.

Can you help me to learn more?

I've seen this clue in the Sydney Morning Herald.
