In May 2008, during plans for a Yes tour to commemorate the band's fortieth anniversary, Anderson suffered an asthma attack, and was diagnosed with respiratory failure. In 2009, Anderson had regained enough strength to complete a solo European tour named Have Guitar, Will Travel. This was followed by a North American leg through 2010. A sample of Anderson's vocals from Mike Oldfield's "In High Places" is prominently featured on "Dark Fantasy" by Kanye West.
