If Mikethong got it right, congrats. That explains why they sounded vaguely familiar to me, and I was actually using the hint correctly, but ran out of time. This was a fun one to hunt for.

I usually have no clue when it comes to the 3 linked jams in the contest, but for whatever random reason I happened to actually be at all 3 of the shows that happened in different eras in different time zones, even though I hadn't seen too many shows through the years of these jams.
