One brief blurb from somewhere:
His songs, from the traditional to newly composed, can be heard on his recordings Border Background, Home and Away, Scottish Voice, Live at the Cactus Cafe and At Home with the Exiles and his most recent, The Edinburgh Rambler.

And a website, although it doesn't contain the lyrics. Go to
