Imagine desperate bloke being stylish performer (5,3)

I believe the answer is:

fancy dan

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

'stylish performer' is the definition.
The definition suggests a singular noun which matches the answer.

'imagine desperate bloke' is the wordplay.
'imagine' becomes 'fancy' (fancying is a kind of imagining).
'desperate bloke' becomes 'dan' (I can't explain this - if you can you should believe this answer much more).
'fancy'+'dan'='FANCY DAN'

'being' acts as a link.

Can you help me to learn more?

I've seen this clue in The Telegraph.
