Unfortunately, this isn't an event being held by WYEP (for now), but Prince doesn't mind inviting people over to his house for a sleep over. He's performing with his new band, 3rdEyeGirl, and the host says that they'll be partying until the sun comes up. The show is Saturday, October 19th, and if you're interested in exploring his studio and home, you can for a mere $50 donation. Be sure to wear your fancy PJs, though. Prince has asked that everyone that comes be dressed to impress.
If you don't want to go all the way to Paisley Park in Chanhassen, Minnesota, you'll have to wait a while for a new tour. Nothing is listed on their website. So make a pilgrimage in your pajamas and get ready to party with Prince until he brings you pancakes!
