All cheering a redesigned musical venue (8,4)
I believe the answer is:
carnegie hall
'musical venue' is the definition.
I know nothing about this answer so I cannot judge whether it can be defined by this definition.
'all cheering a redesigned' is the wordplay.
'redesigned' is an anagram indicator.
'all'+'cheering'+'a'='allcheeringa'
'allcheeringa' is an anagram of 'CARNEGIE HALL'.
Can you help me to learn more?
(Other definitions for carnegie hall that I've seen before include "well-known venue" , "New York concert venue" .)
