Really the more I think about it there are no wrong answers.
...and Wes, you always talk out your ass, that's what I like about you...
Seriously though, I like KC too, they just totally ripped off Led Zep, and I'm okay with that, in fact I think I picked up the s/t on vinyl back in the day and it got a lot of plays!
I agree with Pete, KC is a total rip off of Led Zep on the first album. On their following cd's not so much. But I will say the S/T is my fave.
