I could do that Doc Heesen trick he performed at the Bowie concert in '78 where they lowered him down in a coffin, spot light only on the coffin but the guitar playing through the mass of speakers. He sat up, (playing the guitar which I can't do) and the stage lite up and there was the rest of the band.
The Angels played continuous from start to finish of their set and Doc was still playing his guitar as he stepped back into the coffin and it went up and out of site with the spot light on it the coffin whole time .... when the stage lite up again, the rest of the band and all their instruments were gone ... like they were never there and the sound slowly faded while the crowd went off so loud you couldn't hear anything else ...... an incredible concert ..... and yes, I was actually drug free that day/night and roughly 3 rows from the stage, sitting on the grass .... hard to believe that was 44 yrs ago ..... Now there was a thought for today
