Thanks, Masato! I've been sitting here playing all those clips. What fun. I had forgotten that it was Carter we learned many of those songs from.I remember Wilf Carter/Montana Slim was our favorite in the '40s- until the first time we heard Hank Williams! (But HW didn't yodel much.)
Montana Slim and Elton Britt were my favorite yodelers when I was a kid. Later, of course, I liked Kenny Roberts and some others.
Thanks for reviving some memories for me!
