Elaborate on line in bill, leading man to appeal (6,3,5)

'appeal' is the definition.
(to tickle someone's fancy is to appeal to them)

'elaborate on line in bill leading man' is the wordplay.
I cannot quite understand how this works, but
'elaborate' could be 'fancy' (similar in meaning) and 'fancy' is found within the answer.
'line' could be 'l' (used when specifying particular lines from a poem) and 'l' is found within the answer.
'man' could be 'ethe' and 'ethe' is found within the answer.
The remaining letters 'tick' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...

'to' is the link.
