Take a sovereign for your song

Dear Teachers

I am watching "The Tudors", there is a phrase "Take a sovereign for you song" (below). Please advise.

00:13:25 Good voice.


00:13:29 Take a sovereign for your song.


00:13:32 Thank you,your majesty.

I would guess that the singer was paid one sovereign (old currency) to say thank you for singing.
