As a first draft, tune died away (8)
I believe the answer is:
unedited
'as a first draft' is the definition.
I can't judge whether this defines the answer.
'tune died away' is the wordplay.
'away' indicates an anagram (letters move away from their original places).
'tune'+'died'='tunedied'
'tunedied' with letters rearranged gives 'UNEDITED'.
Can you help me to learn more?
(Other definitions for unedited that I've seen before include "unchanged" , "In the original version" , "Left as seen" , "Not ready for publication" , "Text that's been unaltered" .)
