There's been some recent shuffling among the slate of opening bands on the

Pearl Jam tour. Indie songwriter Sean Lennon, son of the late

Beatle John Lennon, who recently released his first solo LP, Into the

Sun, has been added to the bill with rockers the Wallflowers in

Seattle on July 22. Buzzsaw punks Zeke will join the Wallflowers on

July 21, the first night in Seattle. Finally, power-poppers Cheap Trick

have replaced punk vet Iggy Pop in the lineup for Aug. 20 in Montreal.
