Overkill have been forced to cancel tour dates after frontman Bobby "Blitz" Ellsworth was diagnosed with walking pneumonia.The band had this to say, "We are terribly sorry that we had to cancel our performance last night, but let's put the rumors to rest, before speculation runs rampant.
"Blitz was diagnosed with what is called 'walking pneumonia', and was medically advised to not perform due to it potentially getting worse if he did. When the health risk is no longer an issue, he'll be ready to kick ass once again."
