I think the original is buried somewhere on this forum (or posted by @gazzaredabove 😁), but Glastopedia has run with it and added loads of locations.

It's fully amped and has a PA, but the stage is small. I've seen 3 acts there and they are always stripped back/solo as opposed to full band. Frank T was just him. Ferris & Sylvester was just the 2 of them with a drummer. At a push you might get a 4/5 piece on there but I think it would be a squeeze.
