Drunk turned up and caught a Puccini work (5)
I believe the answer is:
tosca
'puccini work' is the definition.
(I've seen this in another clue)
'drunk turned up and caught a' is the wordplay.
'drunk' becomes 'sot' (both can mean someone who drinks too much).
'turned up' is a reversal indicator.
'and' says to put letters next to each other.
'caught' becomes 'c' (cricket abbreviation).
'sot' backwards is 'tos'.
'tos'+'c'+'a'='TOSCA'
(Other definitions for tosca that I've seen before include "Opera at Ascot?" , "One of Puccini's 19" , "Leaping opera heroine" , "Puccini's jumper" , "Puccini opera set in Rome" .)
