Seeking works for "Earl of Totnes"

The only recordong I know of is per Robin & Barry
Dransfield, on The Rout of the Blues. Unfortunately
There are many words I can't quite get. The following
is the best I could do...

The feast was over at Techam Hall
And the wassail bowl had been served to all
The Earl of Totnes rose from his place
The chanters came in to say the grace.

But scarce was ended this holy rite
There stepped from the crowd a valiant knight
His armor bright and his visage brown
His name was Sir Arthur de Jump a-noun

Good Earl of Totness approached a me
My fleetest courser from Barbary
And whether good or ill betide
A wager with you I mean for to ride

No Barbary Courser do I own
But I have brought the Earl of Devonshire home
I'll write you a wager by land or by sea

Help!
