Looks like a great venue. How were the acoustics? Sometimes things get swamped in church halls. Here the the UK we have a bunch of great Sofar events, even in the North East where I'm located which is usually forgotten.
I've been to a bunch of them and I've never been disappointed. Always interesting venues and great performances.
The hand stamps? Yep, it must be a Sofar thing! :D
Everybody was seated. There was a guest list and participants were not allowed to stand randomly in the church. The acoustics were great. These churches are equipped with organs and sometimes organ concerts take place, so the acoustic was a key feature in their design.
