Song from the past, covered by Scaffold, I enjoyed (5)
I believe the answer is:
oldie
'song from the past' is the definition.
(an old or classic song)
'covered by scaffold i enjoyed' is the wordplay.
'covered by' says the answer is hidden in the clue.
'OLDIE' is hidden within 'scaffold i enjoyed'.
(Other definitions for oldie that I've seen before include "The --, UK magazine" , "forties film, say" , "Venerable person/thing" , "Senior citizen" , "pensioner" .)
