Celebrate around recreation ground -- with fireworks doing this? (8)
I believe the answer is:
sparking
'fireworks doing this?' is the definition.
(fireworks spark when let off)
'celebrate around recreation ground' is the wordplay.
'celebrate' becomes 'sing' (I've seen this before).
'around' is an insertion indicator.
'recreation ground' becomes 'park' (I've seen this before).
'sing' going around 'park' is 'SPARKING'.
'with' acts as a link.
(Other definitions for sparking that I've seen before include "Setting off" , "Stimulating" .)
