ya know, if you want great indoor singing with choreography and excitement you should really check out the barbershop world. ive been singing barbershop since i was nine, and the only reason im not right now is because i wanna march. but its one of those lifetime activities that once i age out ill be back in it, full swing. seriously check out some barbershop on youtube or something. you might enjoy it. im at the international contest in denver right now, so it just stuck out as something that i should guide you to. :)
