Leave a musical group performing? (7)

I believe the answer is:

abandon

'leave' is the definition.
(to abandon is to leave or desert)

'a musical group performing?' is the wordplay.
'musical group' becomes 'band' (band is a kind of musical group).
'performing?' becomes 'on' (as in being on stage).
'a'+'band'+'on'='ABANDON'

(Other definitions for abandon that I've seen before include "Leave high and dry" , "Forsake - careless freedom" , "Leave, desert" , "Desert or yield without restraint" , "Desert; lack of restraint" .)

I've seen this clue in The Times.
