Great number by current British band making comeback? It's Sweet! (8)
I believe the answer is:
sorbitol
'sweet' is the definition.
Both the definition and answer are singular nouns.
Perhaps you can see an association between them that I can't see?
'great number by current british band making comeback?' is the wordplay.
I cannot really see how this works, but
'number' could be 'bit' ('bit' can be a synonym of 'number') and 'bit' is located in the answer.
'band' could be 'o' (I've seen this in other clues) and 'o' is located in the answer.
This may be the basis of clue (or it may be nonsense).
'it's' acts as a link.
Can you help me to learn more?
(Other definitions for sorbitol that I've seen before include "Sugar substitute - lost Biro (anag)" , "Sweetener" .)
