DENVER (AP) — The classic rock band Yes has canceled all concert dates through Feb. 24 because of unspecified medical reasons.

British rocker Yes have canceled their 40th anniversary tour of North America after singer Jon Anderson was diagnosed with acute respiratory failure.

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.

Some of these songs have some good moments but just go on a little too long. Some of them have zero good moments, and then go on a little too long. What they all have in common is that they're too freaking long. Any of these guys ever hear of trimming the fat? Less is more? Your song is too damn long? Any of that ringing a bell, you bloated, self-indulgent rockers?

The story of Yes is as controversial as their music. The twists and turns of the band's career is now told for the first time in a series of exclusive interviews with Yes members past and present for this definitive and fully authorized DVD documentary.
