That first Ratt ep was awesome. I'll check the link but I'm figuring it's the Aerosmith version? Ratt's is better. That ep and the first two albums still get airplay at Casa Carlston to this day, though I never got into anything much past them (a song or two, but that's it). I saw Ratt about as many times as I saw Motley back in the day, as they came up at exactly the same time. I never saw them with Jake E. Lee, but I did see them with Marc Torien on guitar (singer from the Bulletboys). He was a great guitar player in the EVH mold. They always put on a great show and the bassist was pretty good too, though I liked his brother better who was in the band for a while (not too sure where Juan went but eventually he came back).
I like how dirty PJ's voice makes that version sound. Musta been pretty scandalous at the time!
