The Old Reel
Not a lot is known about this tune. I probably first heard it on the 1981 album 'Seal Song' by the Glasgow-based group Ossian.
Scotland: The Old Reel (traditional)
J Murdoch Henderson published The Old Reel in his 1935 collection Flowers of Scottish Melody, saying it was from James Davie's Caledonian Repository, 1840 (although I have not managed to find it there yet). It also appeared sixty years later under the title The Cairngorm Brooch.
Ireland: The Bunch of Keys
The Bunch of Keys is a popular Irish variant, recorded by Joe Burke, Bobby Casey, Paddy Keenan, Johnny Doherty, Kevin Burke, Tommy Potts, and many others. Other Irish versions can be found under the names The Flowers of Limerick and The First House in Connaught.
USA: Paddy On the Turnpike
This tune was recorded in the 1920s by the likes of Fiddlin' Powers and the Kessinger Brothers, and later by Bill Monroe, and just about everyone else!
