'closeness' is the definition.
I don't know anything about this answer so I can't judge whether this works.

'a song and dance about the' is the wordplay.
I cannot quite see how this works, but
'a' is present in the answer.
'about' could be 'a' (abbreviation in Chambers) and 'a' is found within the answer.
an anagram of 'the' is 'eth' which is located in the left over letters.
This explanation may well be incorrect...
