I wouldn't think that Jimmie Rodgers thinks that he is not the "real" one. Those of us who grew up in the fifties remember him as having a number of hits, the last being "English Country Garden" in 1963 or so. Until I did a search on the "net" I'd never heard of this earlier yodelling fella who died in 1933. Before my time I think, I've never heard any of his records anyway. I don't think that yodelling cowboys have ever been too popular over here in the UK.
