Musical group finding port after time (4)
I believe the answer is:
trio
'musical group' is the definition.
(trio is a kind of musical group)
'port after time' is the wordplay.
'port' becomes 'rio' (I've seen this before).
'after' is a charade indicator (letters next to each other).
'time' becomes 't'.
'rio' put after 't' is 'TRIO'.
'finding' is the link.
(Other definitions for trio that I've seen before include "wise men?" , "Three together" , "Ensemble musical piece, eg Beethoven's 'Archduke'" , "Work for three" , "Beethoven's 'Archduke': famous piece written for this ensemble" .)
