While we’re still waiting for a TV show from Les Claypool and Dean Ween, the long-time fishing buddies collaborated musically last night in the Bay Area. On Friday night the Primus bassist sat-in with The Dean Ween Group on a Ween classic at Sweetwater Music Hall in Mill Valley, California.

Claypool emerged to replace Dave Dreiwitz on the title track to the 1997 Ween album The Mollusk. Les has a special relationship with Mickey “Dean Ween” Melchiondo, as the bassist helped convince Deaner to form the Dean Ween Group in the wake of Ween’s 2012 breakup. The Dean Ween Group opened a pair of Summer 2014 shows for Primus which led Melchiondo to write a note to Claypool. “Les Claypool was a great friend to me during the difficult period after my band broke up. It was him that convinced me not to quit music altogether, to start a band with some friends, get in a van and drive around and have fun playing music again, like it is supposed to be. Truth. And he did us a huge solid by putting us on some Primus dates in front of thousands of people. So thank you Les, for being a true friend and motivator and backing it up by asking us to open up for them, it wasn’t even something we solicited, he called me personally. Great dude and a great friend,” the note read.
