I have just finished watching several TV clips of B & T at youtube. There is a clip from an Ozzie & Harriet, two or several from Playboy Penthouse, and an eight part interview and performance from a show called Reveille (as best as I can make it out) from the period of the Hootenanny TV show era (they mention it).

Here be 2 sites:
