I haven't done a slide yet, so here you go! This slide can also be played as a jig. It has been recorded by lots of folks but a great recording is Kevin Burke's "If the Cap Fits."
This is a great one for ornamentation - there are spots in the tune that lend themselves nicely to rolls and other tricks you have in your bag.
And there you go! Now I need to go get ready to go to a matinee showing of Harry Potter 7 Part 2! Squeeeeeeeeeeeeee!
