Fans’ favourite record was ELP bizarrely (5-7)
I believe the answer is:
'fans' favourite' is the definition.
I know nothing about this answer so I can't tell whether this works.
'record was elp bizarrely' is the wordplay.
'bizarrely' is an anagram indicator.
'recordwaselp' with letters rearranged gives 'CROWD-PLEASER'.
Can you help me to learn more?
