Just so you’re not disappointed: No, Les Savy Fav singer Tim Harrington does not jump off the yacht into Lake Michigan. He’s a wild man, and one of the most entertaining frontmen in rock, but he doesn’t have a death wish. Still, he got as crazy as a 100-passenger rented yacht would allow, as you’ll see from the band’s rendition of Alice Cooper’s “School’s Out,” which features a chorus of A.V. Club staff and guests. And for all of your boating party needs, try The Celebration, which launches out of Navy Pier. They were very nice to us.
