It is impossible to underestimate the awfulness that was the prog-rock band, Yes, and their bastard offspring, Asia.

The band Asia have been forced to cancel their upcoming U.K. tour after drummer Carl Palmer was diagnosed with a serious bacterial infection.

The Heat of the Moment hitmakers were due to celebrate their 30th anniversary on the road with a series of gigs, but they’ve pulled the plug on seven shows to allow Palmer time to recover from a severe case of E. coli.
