Wrong one Brendy. The Earl of March's Daughter was written by Lionel McClelland of the group Blackeyed Biddy.

From memory:

Young Toshy Law's a huntin ga'in
And gallant is his deed
For he's ta'en the heart o' Lady March
The fairest maid in Tweed

chorus as hennes remembered

Now the faither he has banished him
For he's below her station.
And Toshy Law has fled to France
To fight for King and nation.

When the lady she has heard the news
That Toshy Law has fled....

Oh bugger, my memory fails me:-(

Guess I'll have to check with the sleeve notes tonight and get back to you.
