Yes I think my mate's tried that but he needs all the other stuff too.
The Punk gigs should be ok with it, but I'm not so sure about the church and the praise band - mind you, he did say their tuning was a bit suspect, perhaps he doesn't want the congregation to think he's not playing correctly. I think quite a few might be past their best now. Shame really as I think a couple of them were, or still are, piano teachers, must be quite difficult if their pitch is "tits up", to use a UK term.
Some of then even sound like Robert Plant in his younger day. Eeeww!
I think he's being a bit optimistic to be fair, he did even say he hoped the switch to piano action make it feel a bit "vintage" - from about 1910(ish) period I think. I suggested he just got an old scrap piano from the local tip. Pity we're in the UK I see there are quite a few over there in the US still.
