Left notes for a young man (3)
I believe the answer is:
lad
'a young man' is the definition.
(I've seen this before)
'left notes' is the wordplay.
'left' becomes 'l' (common abbreviation).
'notes' becomes 'ad' (**).
'l'+'ad'='LAD'
'for' acts as a link.
(Other definitions for lad that I've seen before include "A young chap into ballads" , "Boy, familiar" , "Young fellow" , "Shaver" , "Boy or youth" .)
