My personal favorite song w/yodeling in it is 'Night Rider's Lament' by Mike Burton. 'Lovesick Blues' is another good one and always a crowd pleaser. I do a Tom Dundee(RIP) song called 'Cowboys Born Out Of Their Time' in which I insert a yodel part. Tom always told me he liked my version and was steamed he didn't think of adding a yodel part. RIP Tom, I really miss you.
