umm not too long normally the not main bands play for about 45 mintues to an hour..... I went to a 3 band concert at 8 and ended around like 11 or 12. But the main band played a lot of old songs, and panic! pry wont, because theyre new and dont have alot of classics
If you live in nyc and have gone to roseland ballroom?
Unfortunately the 6 doesn't pass all that close to the Roseland. However that doesn't mean you can't use it to get there. If you take the 6 to Grand Central, from there you can transfer to the shuttle (S). Take the S to it's only other stop, Times Square.
From Times Square, you have a couple of choices. You can either climb the stairs up to the street and walk the ten blocks or so up Broadway to the Roseland, or you can transfer to an uptown 1 train to 50th St. and Broadway, which is just a couple of blocks away from your destination.
