The Evens did this for a kid's show, Pancake Mountain (more on that later). They probably won't play it live, but it's an attestment to how completely amazing this band is. And hilarious. ANYWAY, the song is called Vowel Movement. It teaches you about the vowels, and yes... sometimes Y. (I still can't believe that 20 years after Minor Threat, the lead singer is singing about vowels. Actually, that may make perfect sense.)
As for Pancake Mountain, it may also be the best kid's show ever - check out the
bands that have appeared on it. Bright Eyes! The Fiery Furnaces! The Go! Team! HENRY ROLLINS! THE FLAMING LIPS! and uh... Billy Idol.
