Interesting... I just looked that tune up in the other O'Neill's, and see that in 1001 Gems (which is what I was using above) it's in a major key and sounds pretty much like the clip. But in the bigger, slightly earlier O'Neill's 1850 Tunes, it's in a minor key. Still the same basic melodic shape, but in a minor instead of a major key. Both versions work, though.
