Concert for which a paid player gets a lot (4)
I believe the answer is:
prom
'concert' is the definition.
(abbreviation for promenade concert)
'a paid player gets a lot' is the wordplay.
'a paid player' becomes 'pro' (eg a professional footballer).
'gets' is a charade indicator (letters next to each other).
'a lot' becomes 'm' ().
'pro'+'m'='PROM'
'for which' acts as a link.
(Other definitions for prom that I've seen before include "Esplanade" , "School ball (N America)" , "Classical music concert for which part of the audience stands" , "Short walk" , "Concert - school dance (US)" .)
