WYSIWYG

You're right, Doc did a nice version of the song. He even added a verse to this effect:

"We picked some together, John, Merle and me, Like 'a'talkin to Casey' and ol 'Staggerlee' And 'don't y'bet your money, if you can't afford to lose' and oh how he played them 'Monday Mornin' Blues'"

I've always liked Doc's version, an affectionate tribute to one of my heros by another of them! Thanks for mentioning it.
