The Claypool Lennon Delirium, the project featuring Primus bassist Les Claypool and Sean Lennon, have embarked on their Spring North American trek last week. The trek kicked off with a legendary surprise on April 10th at the Danforth Music Hall in Toronto, Ontario as the group invited Rush bassist Geddy Lee on stage. Lee teamed up with the band to perform a cover of the Beatles’ “Tomorrow Never Knows.”
