Captain cheer? Left at sea with Queen songwriter? (4,6)
I believe the answer is:
cole porter
'songwriter?' is the definition.
(I know this)
'captain cheer? left at sea with queen' is the wordplay.
'captain cheer?' becomes 'cole' (I can't justify this - if you can you should believe this answer much more).
'left at sea' becomes 'port' (I've seen this in another clue).
'with' means one lot of letters go next to another.
'queen' becomes 'ER' (abbreviation for Elizabeth Regina).
'cole'+'port'+'er'='COLE PORTER'
Can you help me to learn more?
(Other definitions for cole porter that I've seen before include "Man responsible for standards" , "US man of note" , "Broadway composer" , "Let's Do It songwriter" .)
