Jon Anderson forced the cancellation of the Yes 40th anniversary tour and is still ill. So the band is hitting the road with Benoit David on vocals.
Who he? He's a singer in Yes tribute acts - although presumably they're not actually tribute acts any more if they feature an actual member of the actual band?
Anderson might be a little nervous about this development, as Yes seem to be enjoying having a singer who's a little more easy to work with:
Also, we hear David brings donuts to rehearsals.
