Even if you weren't born in a small town, you may have some appreciation for the heartland rock of John Mellencamp -- or you can at least hum a few lines to one of his more popular songs.
To mark the occasion of the Farm Aid co-founder's 60th birthday (b. Oct. 7, 1951, in Seymour, Ind.) we're just offering up a couple photos and videos and giving you the chance to say, "Rock on, John."
Tell us in the comments what your favorite Mellencamp song is -- "Small Town"? "Pink Houses"? "Jack and Diane"? Or something else?
