Love being in dance band (4)
I believe the answer is:
hoop
'band' is the definition.
(I've seen this before)
'love being in dance' is the wordplay.
'love' becomes 'o' (In tennis, 'love' means 'zero').
'being in' indicates putting letters inside.
'dance' becomes 'hop' (hop is a kind of dance**).
'o' going into 'hop' is 'HOOP'.
(Other definitions for hoop that I've seen before include "Large ring" , "Wood, metal or plastic band" , "round during dance" , "Circular band, in basketball, say" , "Arch used in croquet" .)
