It’s well known that the guys from Ween are huge fans of the great Bernie Worrell. The band’s lovable guitarist Dean Ween recently had the opportunity to play with Parliament Funkadelic guitarist Michael Hampton, and had scheduled a Dean Ween Group show that was supposed to feature Worrell as a special guest star. Though Worrell had to unfortunately cancel due to his ailing health, the group still played the set, however, dedicating the music as a tribute to Worrell and his legacy.

The Ween-Worrell connection has a much deeper history, as the funk wizard once joined Ween at their performance on September 26th, 2003 in Berkeley, CA. The band hit the Greek Theatre, welcoming out Worrell for an extra funky take on the Ween original tune, “Pandy Fackler.”

Watch some footage of that jam session below, as well as a full-length audio stream of the collaboration.

For the Ween faithful, here’s a playlist of every song from that fateful performance in 2003. Enjoy!
