Bands we organised, nobody wants to hear! (3,4)
I believe the answer is:
bad news
'nobody wants to hear' is the definition.
I can't judge whether this definition defines the answer.
'bands we organised' is the wordplay.
'organised' indicates an anagram.
'bands'+'we'='bandswe'
'bandswe' with letters rearranged gives 'BAD NEWS'.
Can you help me to learn more?
(Other definitions for bad news that I've seen before include "Ill tidings" , "Speedy traveller" , "Someone undesirable (slang)" , "troublemaker" , "dope travelling fast?" .)
