Interviewer: What was the first song you played at the first rehearsal, and how was it?
    Jimmy Page: It was probably "Train Kept A-Rollin'," I think. But we did more than just "Train Kept A-Rollin'" during that rehearsal. But how was it? It... well, we all got into the rehearsal room and played, and it was like earth shattering for each every one of us. That's what it was like.
    Robert Plant: We didn't have any material, did we?
    Jimmy Page: Well, not really. We were just doing whatever. But it was just the intensity of what was going on with the communion, if you like, of the four of us. It was very intense right from that point, there's no doubt about it.
    John Paul Jones: The VERY FIRST Zeppelin rehearsal?
    Jimmy Page: The rehearsals in Ger... yeah.
    Robert Plant: Gerard Street.
    John Paul Jones: Gerard Street, yes.
    Robert Pant: I think we did, uh...
    John Paul Jones: It was like, "What do you know?" "Oh, I don't know. What do you know?" "Oh, I don't know." And then Jim said "Train Kept A-Rollin'."
    Interviewer: No, I meant rehearsal for the O2 show.
    Jimmy and Robert: OH!
    John Paul Jones: Yeah, that's what I was thinking.
    Jimmy Page: You got a little extra there.
    Robert Plant: Fantastic that we... Aren't we coherent? ... What was the first thing that we did? Um...
    Interviewer: You got back together and...
    Robert Plant: Yeah, yeah. I understand the question. Fucking hell.
