In waiting room at London Airport, 1965
Reporter: How long is it since you were last in London?
Dylan: About a year.
Reporter: What's the lightbulb for?
(Dylan holds up an enormous industrial lightbulb)
Dylan: What's the lightbulb for? I thought you would ask me that. No I usually carry a lightbulb. Somebody gave it to me, you know.
Reporter: Sorry, I didn't quite catch the answer
Dylan: Someone gave it to me... a very affectionate friend.
Reporter: Oh, I see.
2nd Reporter: (to Bob Neuwirth) Are you folk?
Neuwirth: Who, am I folk? No, not me. I'm not folk.
3rd Reporter: (to Dylan) What is your real message?
Dylan: My real message? Keep a good head and always carry a lightbulb.
Reporter: Have you tried?
Dylan: Well, I plugged it into my socket and the house exploded.
