Micca, you can keep the Gladiator - it has too many words for me to remember. I'll make sure to suck up be extra nice to Morty.

Just to make an attempt at staying on topic - this is where the song ownership, or perhaps more kindly, song 'guardianship' gets complicated. We travel to a different venue, community, or even country and have to figure out whose toes we might step on. Or maybe it's easier: we can't be expected to know who does which songs so everything's fair game.
