This reel was the first tune ever written by Shetland fiddler Samuel Ian Rothmar Burns, probably around 1960. Spootiskerry is the name of a farm in the author's family. In his tunebook, also called Spootiskerry, he says "Spootiskerry [is] the croft belonging to my late grand aunts, Bella and Joan Nicolson, situated between the village of Sullom, and the new town of Brae." A spoot is a razor clam, one of the edible "ebb meats" taken from the shore at low tide, named because it "spoots" (or spouts) when you disturb it. A skerry is a group of rocks which are only sometimes visible at low tide.
This tune was first printed in 1903 in America, in policeman and Irish traditional music collector Francis O'Neill's Music of Ireland, which contained 1850 melodies.
This tune is probably of early 19th century Scottish origin. It may be descended from Fairy Dance, which is in turn a version of Nathaniel Gow's 1809 tune Largo's Fairy Dance. It was also present in Ireland early in its history. There are several other unrelated musical compositions that use the same name, including a hornpipe and a ballad.
