Blast from the past (5)
I believe the answer is:
oldie
'blast from the past' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for oldie that I've seen before include "Standard song" , "The --, UK magazine" , "Perennially popular song or film, often golden" , "Aged person (colloq.)" , "one who is past it?" .)
