When I first joined King Golden Banshee, the guys in the band were kind enough to give me a copy of an out of print book they used as a source of many of their tunes called, Trip to Sligo. Just learned that it has been reissued and is available from Custy’s in Ennis.
Really nice resource (though quite a few tunes are marked “unknown” – then again, tune names don’t seem to be as important in Ireland as in the States). However, found a link to a list of all the corrections / additions thanks to the hard work of Philippe Varlet back in 1999.
