When Casey came to MD for a show last fall --he tweeted and asked if anyone in the area had an upright bass he could borrow. I remember wondering if anyone would notice the tweet and lend him one. I was hoping so because I wanted to hear him play.
When I got to venue--I saw that someone came through for him

Anyway, in the middle show Casey somehow struck up a conversation with some guy in the audience. I can't remember exactly how it all went down--he may have called out for someone to bring a beer to the stage. Or, he could have asked if anyone knew how to play bass or knew a certain song. Or, it could have even been a pretend heckler. Can't remember--but it was done in a humorous, cool way. So, of course, the guy who lent him the bass started playing it and he did a few songs with the band.
I've also noticed that he has tweeted out to borrow a bass for at least another show or maybe more. In NYC, I'm pretty sure he was using Zac Greenberg's bass who played bass in the Orchestra of People vid. He was there and played bass at the show for a couple of songs
ETA-- I was wondering when you all had dinner with him if he mentioned any future plans like an EP or new cd
