It's too hard for me to narrow my choice to one song and like Kim, I've since them just the one time this past NYE in Philly. I'd say that night "One" totally rocked.
Excuse the pun, but I could help but feel the "oneness" between all the fans and Creed. It was an awesome feeling.
Some of my other favorites were Bullets, Ode, Torn,, What If, Say I, Higher and of course, WAWO. That was an experience in intself to see Scott sing it that night. He was so emotional performing it, it still touches my heart just thinking about it.
