Song was missing verse (4)
I believe the answer is:
lied
'song' is the definition.
(type of German song)
'was missing verse' is the wordplay.
'was' becomes 'lived' (to live is to be).
'missing' is a deletion indicator.
'verse' becomes 'v'.
'lived' with 'v' taken away is 'LIED'.
(Other definitions for lied that I've seen before include "Idle (anag.)" , "conveyed a false impression" , "German Romantic song" , "German air" , "gave a false impression" .)
