"Three Jolly Sheepskins", also known as "Hamilton Races" or "Three Sheepskins" is a Scottish and English air and country dance.
Chappell records that the tune first appeared in Henry Playford's Dancing Master (10th ed.) of 1698. In editions 10 - 16 it was given in D mixolydian. In the last two editions (17 & 18) is was given in A mixolydian.
Another printing appears in London publisher John Walsh’s Compleat Country Dancing Master (1718). Glasgow musician James Aird printed the tune on the same page as several other trade tunes (such as "The Hammermens' March" and "The Taylors' March"), indicating the melody was associated with the tanning trade and the Incorporation of Skinners. "Three Sheepskins" was used as "The Skinners' March". "Three Sheepskins" also appears in Scottish musician and dancing master David Young's MacFarlane Collection (c. 1740). As a song air, “Three Sheepskins” was used in the 18th century ballad operas Polly, The Devil to Pay and The Jealous Clown. It was printed in Barlow's The Complete Country Dance Tunes from Playford's Dancing Master (1986) and Walsh's Compleat Country Dancing Master, Volume the Fourth (1740). It was recorded by Dave Shepherd & Becky Price on Ashburnham and Robin Williamson on Legacy of the Scottish Harpers, vol. 1.
