Indian side in arena with band playing (4,5)
I believe the answer is:
naan bread
'indian side' is the definition.
(I know that naan bread is Indian)
'arena with band playing' is the wordplay.
'with' says to put letters next to each other.
'playing' is an anagram indicator.
'arena' put after 'band' is 'bandarena'.
'bandarena' is an anagram of 'NAAN BREAD'.
'in' is the link.
(Other definitions for naan bread that I've seen before include "Teardrop-shaped accompaniment to an Indian dish" , "Indian staple?" , "Indian food item" .)
