Tay Zonday of "Chocolate Rain" fame recently interviewed Weezer talking about their plans for the coming year. Of some note is the band's plan for a jamming tour:

We're going to go on a tour. It's called the Hootenanny Tour, and it's coming to your town in June. We're gonna bring ourselves and invite a bunch of Weezer fans down to bring their instruments and, uh, jam with us. I don't know, 100, 200 people, whatever. Everyone come down and bring an instrument -- whatever you can play -- and we'll jam out on our songs. Then, in September, we're touring Japan, and in October we'll be touring the U.S., probably in the big rock arenas.
