Although "Beth" is a good song by KISS (the B-Side to "Detroit Rock City"), I would argue that "Forever" is probably a better known power ballad by KISS. I will also argue that one of the power ballad groups that got alot of airplay in my college days was the hairband rockers Warrant. They had a slew of hits in the late 1980's, and to be a hairband getting radio exposure, you had to be a power ballad group.
And don't get me started on the "Cherry Pie" video. :D
Warrant-
The lead singer, Jani Lane, is from my hometown of Akron, OH. I've met him once. Nice guy, but a poster child for "Rock Against Drugs" commercials...he's about 42 but looks 60. I'd put "I Saw Red" and "Heaven" in my top 20, but not my top 10. Good times, good times...
Wow! You sound as if you belonged to teh Kiss Army!!!
