Drunk fans periodically visited composer (5)
I believe the answer is:
dukas
'composer' is the definition.
(I've seen this before)
'drunk fans periodically visited' is the wordplay.
'periodically visited' means one should take alternating letters.
'drunk'+'fans'='drunkfans'
The alternating letters of 'drunkfans' are 'DUKAS'.
(Other definitions for dukas that I've seen before include "French composer, 1865-1935" , "French composer (The Sorcerer's Apprentice)" .)
