Old hit number I am performing with matron (2,10,3)

Ross

I believe the answer is:

mr tambourine man

I'm a little stuck... Click here to teach me more about this clue!

'old hit' is the definition.
I don't know anything about this answer so I can't judge whether it can be defined by this definition.

'number i am performing with matron' is the wordplay.
'performing with' indicates an anagram.
'number'+'i'+'am'='numberiam'
'numberiam' anagrammed with 'matron' makes 'MR TAMBOURINE MAN'.

Can you help me to learn more?

(Another definition for mr tambourine man that I've seen is " Rock song".)

I've seen this clue in The Independent.
