1968, John Lennon and Paul McCartney with guest host Joe Garagiola. It says that this particular episode is "missing" yet a very spotty clip appeared on youtube recently. The transcript is available on DM's Beatle site...I thought this clip was interesting
JG: "If you couldn't have been in music - if it hadn't happened for you - what do you think you would like to do?"
John: "Ahh, I don't know. Films for me."
(Paul relaxes back comfortably)
JG: (pause) "How about you, Paul... I'm not breaking your mood, am I?"
Paul: "No. You're doing great, you know. But, umm..."
Paul: "So, what would I like to have been?"
John: "A policeman."
Paul: (to John) "...no. Not a policeman."
Paul: "Uhh, I don't know, you know. I was nearly gonna be a teacher but that fell through, luckily."
(music swells for a commercial break... Paul begins humming along... girls scream)
JG: (to John) "Why don't you read that (cue card) and see what the reaction is."
