Last night I played with Kinja to see how it would handle a YouTube playlist. As a subject, I did Yoko Ono and John Lennon. Unfortunately, though the draft screen will do a playlist, the embedded display will not properly function at this time.
The YouTube channel BeatleMac7363 has archived Tom Snyder's interview with John on the Tomorrow Show, along with a sample episode from John & Yoko's appearances on Dick Cavett and one from the historic week they spent co-hosting Mike Douglas, where in addition to some regular guests, they welcomed figures from the counterculture such as Ralph Nader, who is featured in the fourth and fifth clip embedded below.
Amazon offers their three Dick Cavett appearances on two disks new, plus they have their week from Mike Douglas on DVD and VHS available from third-party sellers, which I've linked.
