Band originally white hot, no longer 'with it' (3,3)
I believe the answer is:
the who
'band' is the definition.
The definition and answer can be both groups as well as being singular nouns.
Maybe there's an association between them I don't understand?
'originally white hot no longer with it' is the wordplay.
'originally' indicates anagramming the letters.
'no longer with' is a deletion indicator.
'white'+'hot'='whitehot'
'whitehot' with 'it' removed is 'whehot'.
'whehot' anagrammed gives 'THE WHO'.
Can you help me to learn more?
(Other definitions for the who that I've seen before include "British pop group" , "60s rock group" , "Rock group (Tommy, My Generation)" , "Tommy, Quadrophenia rock group" , "Loud rock band" .)
