Morrison's Group HO stored bananas (3,5)
I believe the answer is:
the doors
'morrison's group' is the definition.
I can't tell whether this defines the answer.
'ho stored bananas' is the wordplay.
'bananas' indicates an anagram (bananas can informally mean crazy).
'ho'+'stored'='hostored'
'hostored' with letters rearranged gives 'THE DOORS'.
Can you help me to learn more?
(Other definitions for the doors that I've seen before include "rock band" , "They may provide openings" .)
