World's First Commercial Videotape?

[AUdubon5425]

I'm playing some old records tonight and ran across this interesting statement on the back of an album:

"Audio Fidelity Records produced and released...the world's first commercial Videotape ("Johnny Paycheck" on Audio 20/20 Label) in June, 1966."

Does anyone have any of these videotapes released by Audio Fidelity? Also, what type of machine would they have been played on?

The album containing that statement is "Tailgating with The Dukes of Dixieland" AFSD 6172, 1967 - one of if not the last Dukes release on AF before they signed with Decca.
