Cover art for Granny lyrics by Dave Matthews Band

Granny actually has absolutley no relevance to the song. When Dave can't think of a name for a song, he'll ask a friend of his, I think it was the lighting guy, but i cna't remember off the top of my head, but that guy will give it a name, he's named songs like "Blue Water Baboon Farm" and "Heathcliff's Haiku Warrior". This is another one of his naming. If you want the exact person check out www.nancies.org
