Song from No, No, Nanette (3,3,3)
I believe the answer is:
tea for two
'song from no no nanette' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for tea for two that I've seen before include "Air" , "Song from musical No, No, Nanette" , "Musical number" , "Popular 1925 song (for afternoon drinking companions?)" .)
