I searched the forum to see if this has been posted before and didn't find it, so here it is: Ceolas has a PDF you can print or download of Paddy O'Brien's Sets.

A bit of a quote from the introduction of the tunebook, created by Dave Gabol and John Walsh:
quote, "In the summer of 1995 I was playing in a session at The Barge Inn, aka Larkin's (Garrykennedy Co Tipp). I was chatting to the Landlord Dan Larkin about music in general and suddenly he jumped up and went upstairs. He returned some time later with a very bad photocopy of a series of tunes arranged by Paddy O'Brien for his ceili band. Dan asked me to make copies and get as many people as possible playing the arrangements to keep Paddy's music alive." - end quote
