A while back I checked out The Best of the Johnny Cash TV Show on cd, and that got me hunting some of the clips on YouTube.
My interest was piqued, so you get to watch along.
Cash with Roger Miller doing "King of the Road"
Andy Kaufman doing Elvis
Doing "Blue Yodel No. 9" with Louis Armstrong
One of my top five favorite versions of any song I've ever heard...Cash with Dylan on "Girl from the North Country" - you can catch the rest from Cash's premiere episode here
Neil Young on "Needle and the Damage Done"
Joni Mitchell's prettiest tune "Both Sides Now"
Cash doing "Last Train to Clarksville" with the Monkees
Johnny takes center stage with his trademark "Hello, Bill Walker" and a number of solos from Norman Blake
CCR doing "Bad Moon Rising"
Duetting with Jose Feliciano
Dennis Hopper reading poetry
"Smoke, Smoke, Smoke" by Phil Harris - sort of singing
And a bonus - part one of three with Johnny Cash on The Muppet Show - with the very cool "Ghost Riders in the Sky"
