Performance I saw with very hot dancing (7,4)

I believe the answer is:

variety show

'performance' is the definition.

'i saw with very hot dancing' is the wordplay.
'with' is a charade indicator (letters next to each other).
'dancing' indicates anagramming the letters.
'i'+'saw'+'very'+'hot'='isawveryhot'
'isawveryhot' with letters rearranged gives 'VARIETY SHOW'.

I've seen this clue in The Telegraph.
