Praised duet a lad composed (8)
I believe the answer is:
adulated
'praised' is the definition.
(I've seen this before)
'duet a lad composed' is the wordplay.
'composed' is an anagram indicator.
'duet'+'a'+'lad'='duetalad'
'duetalad' anagrammed gives 'ADULATED'.
(Other definitions for adulated that I've seen before include "Flattered in an obsequious manner" , "Praised" , "given excessive praise perhaps" .)
