Group with single in commercial scrapped (9)
I believe the answer is:
'scrapped' is the definition.
(I've seen this in another clue)
'group with single in commercial' is the wordplay.
'group' becomes 'band' (band can mean a group of people).
'with' is a charade indicator (letters next to each other).
'single' becomes 'one' (a single thing - only one).
'in' means one lot of letters goes inside another.
'commercial' becomes 'ad' (abbreviation for advertisement).
'bandone' inserted within 'ad' is 'ABANDONED'.
(Other definitions for abandoned that I've seen before include "marooned" , "Crazy!" , "without any reservations at all" , "Rejected" , "Left in the lurch, forsaken" .)
