Kesey was diagnosed with diabetes in 1992. In 1994, he toured with members of the Merry Pranksters, performing a musical play he wrote about the millennium called "Twister: A Ritual Reality". Many old and new friends and family showed up to support the Pranksters on this tour, which took them from Seattle's Bumbershoot all along the West Coast, including a sold-out two-night run at The Fillmore in San Francisco to Boulder, Colorado, where they coaxed the Beat Generation poet Allen Ginsberg into performing with them.
