Psychedelic rock band on front of stage for opener (9)
I believe the answer is:
corkscrew
'opener' is the definition.
(tool for opening wine bottles)
'psychedelic rock band on front of stage' is the wordplay.
I cannot quite see how this works, but
an anagram of 'rock' is 'cork' which is present in the answer.
'band' could be 'crew' (I've seen this before) and 'crew' is found within the answer.
A single letter 's' remains which might be clued in a way I don't understand.
This explanation may well be incorrect...
'for' acts as a link.
Can you help me to learn more?
(Other definitions for corkscrew that I've seen before include "handy opener" , "Bordeaux might require this?" , "Spiral device for wine lovers" , "This might help one who gets in the drink" , "Graves opened by this" .)
