Left to go around clubs, being keyed up (7)
I believe the answer is:
excited
'keyed up' is the definition.
(thesaurus)
'left to go around clubs being' is the wordplay.
'left' becomes 'exited' (to exit is to leave or depart).
'to go around' indicates putting letters inside.
'clubs being' becomes 'c' (I can't explain this - if you can you should believe this answer much more).
'exited' placed around 'c' is 'EXCITED'.
(Other definitions for excited that I've seen before include "Agog" , "Worked up" , "in high spirits" , "Hot" , "Aroused; eager" .)
