'me?' is the definition.

'version of g'n's operetta not seeing an end' is the wordplay.
'version' becomes 'middlee' (I can't justify this - if you can you should believe this answer much more).
'of' is an anagram indicator (the answer comes from or 'of' the letters).
'seeing an end' suggests the final letters.
The final letters of 'gns operetta not' are 'sat'.
'sat' with letters rearranged gives 'ast'.
'middlee'+'ast'='MIDDLE EAST'

'to' acts as a link.
