On Dec. 25, 1987, Ted Nugent paid a neighborly visit to David Letterman's Old Fashioned Christmas special. As you can see above, the spirit of the season apparently overcame them both, as they wound up singing "The Christmas Song" together.

We're not sure what's more surprising, the notion that Nugent and Letterman lived right down the street from each other, or the fact that Letterman's an absolutely amazing singer as well as a deft piano player. Seriously, why even keep Paul Shaffer around? Just build a keyboard right into the host desk, like Chevy Chase did on his ill-fated talk show.

Many, many years after this appearance, and after nearly five decades in the rock spotlight, it's sometimes easy to forget that Nugent remains not only a headline machine but also one the ringleaders of what remains one of the finest rock and roll shows you can spend your hard-earned money on.
