For the past twenty five years (to my knowledge) there has been a tune book called "Begged Borrowowed and Stolen" circulating around the Australian folk scene. There are 98 tunes in this book and it is so well known that some musicians just call out the number rather than the names of the tunes .-)
That being said some of the 'sets' are much more commonly known than otheres and you can turn up at any session and these sets will invariably come up
1 South Wind, Munster Cloak,
2 Blackthorn Stick,Rakes of Kildare,Haste to the Wedding
3Joe Burke's Jig, Over the Oceans,Saddle the Pony.
4 Lannigans ball , Top of Cork Road,Tripping up the Stairs
5 Foxhunters Jig, Rocky Road to Dublin
6 Pat Horans #1, Pat Horans #2 Fourty Pound Float. 7 New York Girls, Siege of Ennis, Bog in the Valley.
8 Rakes of Mallow, Davy Knick Knack, Soldiers Joy.

If anyone wants the music for any of these (I don't do MIDI, no facility)drop me an e-mail ed42@4kz.com.au. I'll scan it and send as a JPEG.
