Troupe member, very wealthy participant on stage, ageless (9,6)

'stage ageless' is the definition.
I don't know anything about this answer so I cannot tell whether it can be defined by this definition.

'troupe member very wealthy participant' is the wordplay.
I cannot really understand how this works, but
'participant' could be 'player' (synonyms) and 'player' is present in the answer.
The remaining letters 'strolling' is a valid word which might be clued in a way I don't see.
This may be the basis of clue (or it may be nonsense).

'on' is the link.

Can you help me to learn more?
