Bandleader Monte Mills lesson in the lost art of yodel

Well, now, the way I was taught and what they told me is you get in the shower, you get to turn the water nice and hot, take a good hot shower and get all soaked up, and then just reach over and turn the hot water off, and you'll learn to yodel right then on the spot. You can just find a note and then slide it up until you hit that falsetto part, and learn how to go back and forth there. Oh, oh, oh. And then you can start adding vowels like that. You see the yodel is not exactly what you call a dependable thing. Some days it's not too bad, some days it's like it is today.
