Lloyd-Webber musical touring clubs everybody boos (8)
I believe the answer is:
catcalls
'boos' is the definition.
The answer and definition can be both related to communication as well as being plural nouns.
Perhaps there's an association between them I don't understand?
'lloyd-webber musical touring clubs everybody' is the wordplay.
'lloyd webber musical' becomes 'cats' (I've seen this before).
'touring' indicates putting letters inside (tour can mean to go around).
'clubs' becomes 'c' (abbreviation in card games).
'everybody' becomes 'all' (all people).
'c'+'all'='call'
'cats' going around 'call' is 'CATCALLS'.
Can you help me to learn more?
(Other definitions for catcalls that I've seen before include "Shrill whistles of disapproval - feline?" , "Shrill disapproving whistles of feline origin" , "Derisive shouts" .)
