Progressive rock supergroup Yes are to hit the road for their 40th anniversary tour with departed keyboard player Rick Wakeman's son OLIVER as a new recruit. Wakeman Sr. explained his reasons for not taking part in the 26-date North American tour in a post on his website, but it appears his son doesn't share his father's fears that Yes are touring too often. He'll join band founders Steve Howe and Jon Anderson when Yes perform at Canada's Quebec City Festival in July (08) at the start of the month-long trek. In the explanation on his website, Rick Wakeman writes: "My major concern was that of over-touring, which I felt Yes had done since 2002 with far too many shows, especially in America which for me diminished the 'specialness' of the band." Billboard.com reports this marks the fifth time Wakeman has quit the band.
