8 Is Late

I'm thinking about the problems of my local orchestra, but this applies generally to other similar artistic endeavors. I don't have kids, work at home, and live in the city within easy distance of theaters/orchestra/etc... and I find the standard 8 o'clock start time - which means home by 11ish - to be a bit late. I'm curious if earlier starting times for such events would more appealing for people, especially the work in the city but need to commute back to the burbs crowd who might be more likely to stick around after work.
