Hrm. Following the Elvis theme, how about "Can't help falling in love" for Clark, or "Forever and Ever, Amen" by.. hold on.. Randy Travis. I don't know about Lois, it probably depends on the time frame. "I Will Survive" by Gloria Gaynor? laugh

BTW, if you're sticking with the show's timeframe, Britney Spears wouldn't be around. At that time, she was still on the New Mickey Mouse Club. Though I do have a rendition of "Can't Help Falling In Love" by her and the rest of the cast...

"You need me. You wouldn't be much of a hero without a villain. And you do love being the hero, don't you. The cheering children, the swooning women, you love it so much, it's made you my most reliable accomplice." -- Lex Luthor to Superman, Question Authority, Justice League Unlimited
