I got it, Stanton. Yes, he does shift the pitch up, but while I notice it, it doesn't really interfere with my ability to listen. I'm pretty sure I've done It. if I'm trying to learn songs, it's not a problem if I can figure out what the tune's supposed to be.

As a kid, I managed to learn songs from my completely-tone-deaf father. Not sure how I did it, but it was a useful skill. The tune of "The Bush of Australia" is pretty complicated, and I'd tend to give Pardon credit for what he did well.
