The Petra Zone

I was wondering if anybody here has any rare live recordings of John's time in Head East? I know there are a few people that came to know Petra through following John after his departure from Head East... I'd love to find ANY video footage of the band performing live aswell as audio recordings in any form (soundboard recordings, audience recordings..whatever)

Thanks

To my knowledge, the band did release a live album or two, but I don't know if they're still available.
