Cover art for Do It Clean lyrics by Echo and the Bunnymen

I don't think this is specifically about coke, as about all the drugs. They did snort a lot of coke, but they also spent a lot of time on acid, and generally took whatever pills anyone had. Quoting Ian: "Pretty much everything but smack. No, I think I did smack once by accident because there was nothing else around." The title "do it clean" does sound specifically coke, but a lot of the other lines fit acid, amphetamines, etc. better—or just all of them.

Then-manager Bill "KLF" Drummond says this song was kept off the album and buried as a b-side of a non-album single, even though it was an obvious hit, because it was also too obviously a drug song, and the label wouldn't have allowed it. Ian said that was BS, and it was left off the album because the original version sucked, and it wasn't until they came back and recorded a totally different version that it was worth releasing. Who's remembering right? Who knows. But foreign labels apparently had no problems with the song—most of them added it as a bonus track—even if it didn't appear on LP in the UK until the best-of half a decade later.
