Geddy Lee made a surprise appearance during The Claypool Lennon Delirium's concert Wednesday night (April 10th). The Rush legend joined a collaboration between Primus bassist Les Claypool and Sean Lennon on stage at the Danforth Music Hall in Toronto, Canada. Fan-filmed footage shows the trio covering The Beatles' “Tomorrow Never Knows.”

According to Blabbermouth, Lee's friendship with Claypool dates back to the 1990s when Primus opened for Rush.
