Come again for a dance (6,2)
I believe the answer is:
excuse-me
I believe this is a double definition.
'come again' is the first definition.
(I've seen this before)
'dance' is the second definition.
(I've seen this before)
'for a' is the link.
(Other definitions for excuse-me that I've seen before include "Dance where one takes another's partner" , "Dance during which one changes partners" , "Apology for interruption" , "Phrase to catch attention or apologise" , "Dance where partners swapped" .)
