Song reflecting one's lack of interest in swingers' clubs? (3,3,4)
I believe the answer is:
any old iron
'song' is the definition.
(I've seen this before)
'reflecting one's lack of interest in swingers' clubs?' is the wordplay.
I cannot quite understand how this works, but
'of' could be 'o' and 'o' is found within the answer.
'one' could be 'an' (I've seen this in other clues) and 'an' is found in the answer.
This may be the basis of clue (or it may be nonsense).
(Other definitions for any old iron that I've seen before include "Number" , "chosen at random by golfer?" , "Song made famous by Harry Champion" , "Scrap request" , "Music hall song -- scrap merchant's call" .)
