I have an embarrassing story to tell.
The week before courses started at the University of Saskatchewan used to be (maybe still is) called Frosh Week - a week for first year students to get organized, to get to know the campus and have a little fun before the hard work begins.
One night during Frosh Week my roommate and I went to a huge dance at the sports arena. There were a few hundred people there. We stayed there through the evening and had an okay time, not great, but sort of okay. As we were walking home we passed the Memorial Union Building (the MUB) where we could hear a pretty good band playing. We stopped and listened for a while and could have gone in (for free) but we were pretty tired so we headed home instead. The band was - you guessed it - Buffalo Springfield. So I've heard Buffalo Springfield in person but never seen them.
