Paul, thanks for the comparisons between Whitman and Ifield. I enjoy Whitman more now than I did in the 50s and 60s. I did like the Ifield recordings when they were first issued but the one song I recall from those days is "I Remember You" which was popular in the U.S. Though it had voice breaks I did not think of it as a yodel song. I did not hear Ifield's serious yodels until much later.
