this is a live performance by a great band. I first heard their cover of "Psychotic Reaction" back in about 1984, thanks to a pen pal. and I had heard of the album "A Date with Elvis" before that, but only because of an unnamed song about a dog and a cat. it was never released in this country until the CD came out.
so this is the live performance, which is also great. one of the best things about the Cramps is they didn't use a lot of studio tricks to make themselves sound better. they just played the way they played. so many bands change the way they sound to get a hit or use a producer and studio musicians to "help" out, it seems false advertising to me.
