Disc unaltered for Manchester band (5)
I believe the answer is:
oasis
'manchester band' is the definition.
(I've seen this before)
'disc unaltered' is the wordplay.
'disc' becomes 'O' (disc-shaped letter).
'unaltered' becomes 'as is' (ie something left 'as is').
'o'+'asis'='OASIS'
'for' is the link.
(Other definitions for oasis that I've seen before include "place of relief" , "Fertile spot in desert" , "A place of safety or sanctuary" , "where palms grow" , "Q-and-A game" .)
