Fallon begins with a mellow performance of Young’s 1972 hit “Old Man,” perched on a stool and hunched over an acoustic guitar. Then, after the first chorus, the real-life Neil Young walks on stage, dressed exactly the same as Fallon, and joins in. Obviously the real Neil Young has more soul and depth and wisdom and Canadian-ness in his voice, but Fallon totally holds his own. ### Photos: David Letterman’s Early Career  One of David Letterman's earliest roles before he made it as a television host was as a guest star on Mork & Mindy.
