And if there were 50,000 people that'd only be 20 cents each, wouldn't it? But it might get a wee bit crowded.

I think there is an upward limit for any kind of social group. Get too big and it turns into another type of group. A folk club where 20 or 30 people get together and exchange music is a totally different animal from one where an audience of 1000 listens to a guest performer. The latter is a better way of making money (or losing money). But the former is probably a better way of making music and making friends.
