1. Finding out that the opener, Mark Knopfler, is responsible for writing the riff that's featured in the now-no-more CBC Radio show "Dispatches" (it's part of a Knopfler song! I had no idea);
2. (Much more exciting!): Dylan performing a cover song (wow!) and speaking an extra three whole sentences to the crowd! This show was a rare treat indeed.
P.S. The mystery cover song was by Gordon Lightfoot (another song I didn't know... I guess I have to expand my listening beyond Dylan and CBC Radio). It's funny... I remember Dylan played "I'm not supposed to care" at Maple Leaf Gardens in Toronto 1998 - but that was because Lightfoot was in the audience (or, at least, it seemed pretty likely that this was the reason, since G. L. was sitting right there.) But maybe that's just something Dylan likes to do when he's in Canada. Ah well, what does it matter... it still was lovely.
I have drawn quite a few other comic strips about Dylan shows. A couple of them are online, and you can see them here. One of these days I'll get around to putting some of the others up.
