Vain teen lost touring US city whatever happens (2,3,5)
I believe the answer is:
in any event
'whatever happens' is the definition.
(I've seen this before)
'vain teen lost touring us city' is the wordplay.
I cannot quite understand how this works, but
'city' could be 'ny' (I've seen this in other clues) and 'ny' is found in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for in any event that I've seen before include "No matter what happens" , "Whatever happens" , "Where the athletic all-rounder may be found" , "A versatile athlete may be" , "Where all-round sportsman may compete" .)
