Composer, oddly drunk, playing (5)
I believe the answer is:
dukas
'composer' is the definition.
(I know that Dukas is a composer)
'oddly drunk playing' is the wordplay.
'oddly' means one should take alternating letters (letters in odd-numbered positions).
'playing' becomes 'as' (I've seen this in other clues).
The alternating letters of 'drunk' are 'duk'.
'duk'+'as'='DUKAS'
(Other definitions for dukas that I've seen before include "French composer, 1865-1935" , "French composer (The Sorcerer's Apprentice)" .)
