seanc, i am in the same boat. i live in new york, and shows dont even *start* till like 10 pm. so if i want to go see a band and still get up with more than 15 minutes getting-ready time before i jump on the train, i'm just SOL the next day.
i also know that i am the type of person who needs a lot of sleep -- if i dont get 8 hours, i may not feel it the next day, but within a few days i will be down for the count and drinking cuppa after cuppa to stay awake during the day.
ah the travails of being a musician and a corporate whore at the same time
