Yo! So I learned a reel today. Well, actually I learned an old-time tune a little earlier, but then I really felt like doing an Irish tune instead so then I learned this one. The old-time tune I deserted is called Half-Past Four (another Ed Haley tune) and it's very cool so I think you should learn it too.
Anyway, Master Crowley's is a fun reel in E minor/dorian. I learned my version mostly from a youtube video of Kevin Burke playing it in a set of reels, which you can see here. So I hope you enjoy!
If you think that stuff there at the end is something you simply can't live without, I have good news: you can order Killarney's Pull the Knife over at www.killarney.bandcamp.com.
