I was living in San Antonio TX back in the 80's and KISS 99.5FM
was my radio station of choice back then. They were really hot on "Seventh Star"
and gave it heavy rotation on their playlist. I always flash on "Danger Zone"
when I think back to that time. I do recall hearing on the syndicated show "Power Cuts"
before the album was released that Tony Iommi was going to use either Glenn or Steve Marriott to do the vocals. And the story they gave at the time of Glenn's departure was that his knee had given out and he had fallen face down and broken his nose. It would be several years before I heard the real story....
But "Heart Like A Wheel"
would be killer to hear live!
