John, on record knightly (5)
I believe the answer is:
elton
'john' is the definition.
(musician Elton John)
'on record knightly' is the wordplay.
I cannot quite understand how this works, but
'on' could be 'to' and 'to' is present in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for elton that I've seen before include "One John" , "Let on he's John, the singer" , "Sir - - John, singer songwriter" , "First name of singer/songwriter born Reginald Dwight in 1947" , "..... Jonn (musician)" .)
