Tango with novel footwear in song from musical (3,3,3)
I believe the answer is:
tea for two
'song from musical' is the definition.
(song from the musical No No Nanette)
'tango with novel footwear' is the wordplay.
'tango' becomes 't' (phonetic alphabet: alpha, bravo, charlie etc.).
'with' is a charade indicator (letters next to each other).
'novel' is an anagram indicator.
'footwear' anagrammed gives 'eafortwo'.
't'+'eafortwo'='TEA FOR TWO'
'in' acts as a link.
(Other definitions for tea for two that I've seen before include "Musical number" , "Song from musical No, No, Nanette" , "Popular 1925 song (for afternoon drinking companions?)" , "Air" .)
