I uploaded a new tin whistle lesson video to my YouTube channel, covering the tune Leslie's March (aka The March from Oscar to Malvina). This was one of the first tunes that I learned by ear, picking it up first from a Chieftains record when I was about sixteen. I then heard it a few years later on the first Solas album, which was one of those records that really impacted me as I was learning to play. For a while it was the only tune that I could play at Solas-speed (read: fast!)
It's a great three part tune in D and, while it doesn't come up much at sessions anymore, it's a great one to pick up. Check it out here if you're so inclined.
