Which Wizard Are We Talking About?

I don't have audio to substantiate this, but my roommate and I heard a girl singing a song about "longing to see the Wizard." The problem is that both of us are sure it's not a Wizard of Oz song. Was this girl singing a KKK devotional song? Does the KKK have devotional songs? We know they have a glee club, so they must have devotional songs.
Now that I remember, if you see Hate Rock on The History Channel or Discovery, watch it. Andy Kline and I saw it. It's better than you could imagine.
