Drinking spree of new head of drama surrounded by ale (6)
I believe the answer is:
bender
'drinking spree' is the definition.
(I've seen this before)
'new head of drama surrounded by ale' is the wordplay.
'new' becomes 'n'.
'head of' suggests taking the first letters.
'surrounded by' is an insertion indicator.
'ale' becomes 'beer' (I've seen this before**).
The initial letter of 'drama' is 'd'.
'n'+'d'='nd'
'nd' inserted inside 'beer' is 'BENDER'.
'of' acts as a link.
(Other definitions for bender that I've seen before include "many a joint, maybe" , "makeshift shelter" , "Wild drinking spree" , "one twists" , "Binge on drinks" .)
