Thanks Joe.
I got the song from Dave Burland who sang : "to drive poor Davy out". I simply put in a version of my own name as most singers would.
Also, with a traditional song I like to change one or two words to put my own mark on it , so to speak. These changes are insignificant to the meaning of the song but give it character to me.
I didn't know that Sam Larner sang the song but what a great singer that man was.
