Hi, Don. A few months ago we had a thread on Yodelling and Yeats which highlighted a video of the Riders in the Sky. Unfortunately, the video disappeared from YouTube.

Ranger Doug of the Riders in the Sky was a wonderful yodeller.

Much to the bafflement of my cat, I have been listening to yodelling of all kinds on YouTube. The variety is amazing. It ranges from comic to reverent in tone and features men, women, soloists and groups.

I have also discovered that against all logic, and against all supposed cultural norms, that yodelling is very exciting and beautiful. It stirs the inner being somehow.

For example, there's a popular video of a little girl, Taylor Ware, singing 'He Taught me to Yodel' on the TV show 'America's Got Talent.' One of the judges is a very sophisticated, very urban-looking black woman, supposedly the antithesis of the yodeller. Yet she loves it! She's obviously pleased and excited by the sound.

Another great yodeller is Kerry Christensen. He has a beautiful warm baritone voice and incredible yodelling technique. You can find lots of his stuff on the web.
