One to deliver notes and perform with Free and Queen (8,5)
I believe the answer is:
dispatch rider
'one to deliver notes' is the definition.
I can't judge whether this definition defines the answer.
'perform with free and queen' is the wordplay.
'perform with' becomes 'dispatch' (I can't justify this - if you can you should give a lot more credence to this answer).
'free' becomes 'rid' (to be free of something is to be rid of it).
'and' is a charade indicator (letters next to each other).
'queen' becomes 'ER' (short for Elizabeth Regina ie Queen Elizabeth).
'dispatch'+'rid'+'er'='DISPATCH-RIDER'
'and' is the link.
Can you help me to learn more?
(Other definitions for dispatch rider that I've seen before include "One carrying messages by motor-cycle" , "Cyclist bearing messages" , "He performs emergency delivery" , "He has urgent message" , "Mounted messenger" .)
