I have 6,709 songs in iTunes, including this one.
This song, along with a whole CD of baseball songs was a gift from Jack, the Baseball Dad. It was a surprise he has apparently sent out to others as well. I thought I'd see if I could find a video of one of the songs. Say Hey (The Willie Mays Song) is pretty obscure (at least to me) but here's what I found. Thanks again Jack!
