Jesters performing a loud solo? (5)
I believe the answer is:
fools
'jesters' is the definition.
('fool' can be a synonym of 'jester')
'performing a loud solo?' is the wordplay.
'performing' indicates anagramming the letters.
'a loud' becomes 'f' (A musical term).
'f'+'solo'='fsolo'
'fsolo' with letters rearranged gives 'FOOLS'.
(Other definitions for fools that I've seen before include "Deceives" , "Proverbially, they rush in" , "'... rush in where angels fear to tread'" , "Tricks" , "' - - Rush in', song" .)
