Young Frankenstein and are new musicals, not revivals. Legally Blonde, a musical based on a popular movie like Hairsray, is doing well. Other revivals do well too. The revival of Kander and Ebb's Chicago has been running since 1996.
BTW, I got young Frankenstein tickets for $46.50 and I'm getting spamalot tickets for $59. A $400 ticket is extremely rare, if it has happened.
Where’d you get the tickets? I know I would love to see Spamalot before it closes, and I’d also like to see Lion King and Phantom of the Opera at some point. However, I’m kinda tight on cash, and while tickets aren’t $400, they’re usually out of my price range. I actually got to go see Rent for $20 almost 2 years back, but those were group, school-subsidised prices. Anyways, wasn’t there some kind of kiosk thing somewhere around Times Square that sold cheap Broadway tickets?
