Gives me goose bumps just thinkin' about it.
A little story on that one.
I picked up a bootleg album in the early eighties called "Dead Out West" (album as in vinyl) with this killer HTH. Fast forward to CD time (it's a shame but I hardly use my turntable anymore!) and my discovery of archive.org and I figured let me see if they have the show. One problem, no date on the album. I searched for Hollywood Palladium since that was the only info and eventually located the show. I even think it's the same source.
The whole show is pretty good.
