gigs like that rule because everyones just out to have fun and there's no competition or bitching or whatever and no one cares if it's not perfect
glad you had fun and I agree with summer of 69. it's amazing how much easier it is to sing even dropped half a key from D (something people might want to consider when bashing Jon for not singing in the original keys)
im hopefully having a party barbeque thing at the end of the month and I'm wanting to do a gig in my living room for it so hopefully it'll be as cool as yours
