Where can i obtain a copy of an old Johnny Carson show ? [ USA]?

Question

I would like a copy of Johnny Carson t.v show when Bay City Rollers first hit USA.

Answer 1

You'll have to go to the Carson estate's official website for information.

Since this is from after 1972, the episode exists in their archive (as you might've guessed, most early episodes were erased or destroyed by NBC prior to 1973).

An alternative is the music video tape-trading underground (there are some who deal with rare TV appearances); some others sell their wares in Goldmine Magazine's classified ad section.

Answer 2

ebay

Answer 3

Some of his old shows are out on DVD.  Did you check youtube.com?
