Gather round the bright little man holding the money that's left (5)

I believe the answer is:
rally
'gather' is the definition.
(rallying is a kind of gathering)
'man holding the money that's left' is the wordplay.
'man' becomes 'ray' (Man Ray was a 20th-century artist).
'holding' indicates putting letters inside.
'the money' becomes 'l' (L can mean 'pounds').
'that's left' becomes 'l' (common abbreviation).
'l'+'l'='ll'
'ray' placed around 'll' is 'RALLY'.
'round the bright little' is the link.
This may not be correct. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for rally that I've seen before include "Pick up" , "Arouse for action" , "Marshal" , "Call to arms - series of strokes" , "motoring event" .)
