Booze keeps shrew mad for musical man (8)
I believe the answer is:
gershwin
'musical man' is the definition.
The definition suggests a singular noun which matches the answer.
'booze keeps shrew mad' is the wordplay.
'booze' becomes 'gin' (gin is a kind of booze).
'keeps' indicates putting letters inside.
'mad' indicates anagramming the letters.
'shrew' is an anagram of 'ershw'.
'gin' enclosing 'ershw' is 'GERSHWIN'.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for gershwin that I've seen before include "George and Ira ..., American musical brothers" , "George ......, composer of 'Porgy and Bess'" , "I Got Rhythm composer" , "US composer" , "Ira and George, US brother composers" .)
