There can't be many arguments that Carl Perkins is the true king of rockabilly in it's purest form. Check out these clips that run through the years. The Ranch Party clip is phenomenal. What a find these old clips were - footage that we never dreamed we'd see.
Your True Love (from Ranch Party tv show)
Turn Around (from Nashville Now - he was a great rockabilly, but just as awesome at country music)
Johnny Cash medley 1974
The Birth of Rock 'n' Roll ( from Class of '55)
Blue Suede Shoes/Matchbox medley from 1971 - I'm not sure which was worse, the waistcoat or the dance steps! The rest is great though.
TV chat with Scotty Moore
Matchbox with Duane Eddy and the Mavericks (what a line-up)
