Wildness in musicians performing? (7)
I believe the answer is:
abandon
'wildness' is the definition.
(synonyms)
'musicians performing?' is the wordplay.
'musicians' becomes 'aband' (I can't justify this - if you can you should believe this answer much more).
'performing?' becomes 'on' (as in being on stage).
'aband'+'on'='ABANDON'
'in' is the link.
Can you help me to learn more?
(Other definitions for abandon that I've seen before include "Permanently desert" , "Lack of inhibition; desert" , "Leave (a place) for ever" , "Wantonness: desert" , "scrap" .)
