Note service returning to this point (2,3)
I believe the answer is:
so far
'to this point' is the definition.
(I've seen this before)
'note service returning' is the wordplay.
'note' becomes 'so' (musical note).
'service' becomes 'RAF' (Royal Air Force).
'returning' says the letters should be written in reverse.
'raf' reversed gives 'far'.
'so'+'far'='SO FAR'
(Other definitions for so far that I've seen before include "Up until the present moment" , "to a certain degree" , "To this point" , "till now" .)
