Recalls Q&A with local Yank about old songwriter, the last favouring Hit not a million miles from Rivers of Babylon? (3-4)

'recalls qa with local yank about old songwriter the last' is the definition.
I don't know anything about this answer so I cannot tell whether this works.

'favouring hit not a million miles from rivers of babylon?' is the wordplay.
I cannot really understand how this works, but
'favouring' could be 'pro' (I've seen this before) and 'pro' is found in the answer.
'a' is present in the answer.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?
