65: "Stairway to Heaven" vs. "Free Bird" (w/Andrew Unterberger!)

<p>It's the big one. The episode this show was invented for, the two towering titans of classic rock, the most requested song on the radio of all time vs. the most requested song live of all time. Will Lynyrd Skynyrd's "Free Bird" reign as the greatest guitar-solo-heavy epic of all time or will it be denied by "Stairway to Heaven" by Led Zeppelin? </p>
