Elton John, say, occasionally down-right out there! (3,6)

'elton john' is the definition.
(I know that elton john can be written as Reg Dwight)

'say occasionally down-right out there' is the wordplay.
I cannot quite see how this works, but
'say' could be 'eg' (short for 'exempli gratia', 'for example' in Latin) and 'eg' is found within the answer.
'down' could be 'd' and 'd' is present in the answer.
'right' could be 'r' (common abbreviation) and 'r' is found within the answer.
The remaining letters 'wight' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...

Can you help me to learn more?
