Donna Jean & the Tricksters keyboardist Mookie Siegel took a few days off the road for family reasons last week. As a result, Pete Levin, who played with the Zen Tricksters in 2001 and 2002, sat in with the group throughout its performance at Teaneck, NJs Mexicali Blues. Levin appeared on both Grateful Dead favorites like Bertha, Ship of Fools and Playing in the Band, as well as tracks from the new _ Donna Jean & the Tricksters_ release like All I Gotta Say. Siegel will rejoin Donna Jean & the Tricksters for a live broadcast on Sirius The Grateful Dead Channel from 9-10 PM this evening.
