"[Iggy] encouraged me to play piano with him [on the first 1977 tour] and I thought the idea was thoroughly enticing and very tempting and I did it for the nerve of it really. I never enjoyed a tour so much, because I had no responsibilities on my shoulders at all, I mean I just had to sit there, drink a bit, have a cigarette, wink at the band, I mean ya know, and watch him."

David Bowie, Zigzag, January 1978
