Recorded, thanks to the piano man (5)
I believe the answer is:
taped
'recorded' is the definition.
(taping is a kind of recording)
'thanks to the piano man' is the wordplay.
'thanks' becomes 'ta' (UK informal version of 'thank you').
'to the piano' becomes 'p' (musical abbreviation).
'man' becomes 'ed' (short for Edward).
'ta'+'p'+'ed'='TAPED'
(Other definitions for taped that I've seen before include "On record; tied up" , "recorded" , "put on record" , "Bound" .)
