There is another tune by the same name, a great hornpipe in A major, composed by Scott Skinner. It’s available on here as well, under Hornpipes.
Re: Frank Gilruth
Peter Milne also wrote a strathspey with the same name. The subject, Frank Gilruth, was born in Sanquhar near Gartly, Aberdeenshire in 1853. He studied teaching, spent a little time in Edinburgh, and in 1882 he went to work at Dumfries Academy until his death in 1915. He was a fiddler and a great admirer of James Scott Skinner (and, I’m guessing, Peter Milne), and he composed tunes in the Scots idiom, mostly hornpipes. His slow air “Farewell to Gartly” was published in Skinner’s Harp & Claymore Collection (1903) and four of his tunes were published elsewhere in 1904 and 1910.
