There is at least one set of words to Niel Gow's Lament for his second wife; I heard them sung on Radio Scotland (Robbie Shepherd's programme, "The Reel Blend") about ten or fifteen years ago, by Anne Lorne Gillies. The last line of each verse ran, "my fiddle and me", so presumably the song was based on the story mentioned in GUEST info above. Robert Burns provided words to the Lament for Abercairney (beginning, "Where, braving angry Winter's storms/The lofty Ochiuls rise"), and in his various notes on Scottish songs and airs it's pretty clear he knew of the Gows' habit of appropriating or adapting melodies ("This air is claimed by Niel Gow, who calls it the lament for his brother Donald", for instance). There's another set from the nineteenth century, each verse ending, "Gude Abercairney's gane".

Oh; with regard to fiddlers' fondness for the instrument, it's related of Peter Milne, "The Tarland Minstrel" and associate of J.S.Skinner, that he said he "loved the fiddle that much I could crawl inside and keek oot o' the F-holes"
