David Gilmour:
«There were two other recording studios in operation there at the time, and we would be in one room and there'd either be the Beatles or the Hollies or the Pretty Things or Roy Harper or any number of other people um, recording at the same time, and we would get to know all these people of course, and we'd sit, you know, down in the EMI canteen and we'd chat with these people and stuff, and we got to know Roy quite well. Roy was always hustling, saying, you know, "let me do something", "let me sing something", "let me write some words for you or something".
We were always saying "Fuck off Roy!", I mean - or, "No no Roy!", I mean... sorry, we are on radio. And, you know, he just obviously came in the room, I can't really remember - he obviously came in the room at a certain point when we were doing that song and said "Hey! let me sing that!" and we said "Oh, all right, off you go, here's the words" and, you know it wasn't a thought-out thing. We didn't think "Hey, we must get Roy Harper to sing this song". I mean it's just one of those things that happens on the day, at that moment in time, in the studio, erm, and boom - there it was. And we thought "Hey, that's OK". Well, I thought it was great. Roger didn't like it that much actually»

Roger Waters:
« ... a lot of people think I can't sing, including me a bit. I'm very unclear about what singing is. I know I find it hard to pitch, and I know the sound of my voice isn't very good in purely aesthetic terms, and Roy Harper was recording his own album in another EMI studio at the time, he's a mate, and we thought he could probably do a job on it »

Roger Waters:
« For example, 'Have a Cigar'. The verses, (tune and words) were all written before I ever played it to the others. Except the stuff before and after the vocal, that happened in the studio. The same with 'Welcome to the Machine' -- the verses were done, but the run up and out was in the studio. 'Dark Side' was done much more with us all working together. We all sat in a room for ages and ages -- we'd got a whole lot of pieces of music and I put an idea over the whole thing and wrote the words. Having laid lyrics on the different bits we decided what order to put them in, and how to link them. It wasn't like the concept came first and then we worked right through it »
