In Hamburg the waiters always had Preludin - and various other pills, but I remember Preludin because it was such a big trip - and they were all taking these pills to keep themselves awake, to work these incredible hours in this all-night place. And so the waiters, when they'd see the musicians falling over with tiredness or with drink, they'd give you the pill. You'd take the pill, you'd be talking, you'd sober up, you could work almost endlessly - until the pill wore off, then you'd have to have another.
