Dance with the girl to an orchestra (8)
I believe the answer is:
saraband
'dance' is the definition.
(saraband is a kind of dance)
'with the girl to an orchestra' is the wordplay.
'with' says to put letters next to each other.
'the girl' becomes 'sara' (**).
'to an orchestra' becomes 'band' (I've seen this before).
'sara' put next to 'band' is 'SARABAND'.
(Other definitions for saraband that I've seen before include "Stately dance" , "Old, courtly dance" , "dance music" , "Slow Spanish dance" .)
