Young knight and classical composer having role reversal (8)
I believe the answer is:
bachelor
'young knight' is the definition.
'bachelor' can be an answer for 'knight' (bachelor is a kind of knight). I am not certain of the 'young' bit.
'classical composer having role reversal' is the wordplay.
'classical composer' becomes 'bach' (Johann Sebastian Bach. I am not sure about the 'classical' bit.).
'having' is a charade indicator (letters next to each other).
'reversal' shows that the letters should be reversed in order.
'role' in reverse letter order is 'elor'.
'bach'+'elor'='BACHELOR'
'and' is the link.
Can you help me to learn more?
(Other definitions for bachelor that I've seen before include "He's not married" , "leading man at start of Wedding Cantata" , "Unmarried person" , "Unmarried man (with a degree?)" , "Single person" .)
