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

Hmm, what is it that Mac is doing clean? Not drugs, bearing in mind this was an early song, around 1980... if you've ever seen the Bunnymen live though, you'll know that it's traditional for people to 'point' their shirts at the band during this song. Because "washing your clothes" is as good a meaning for this song as any!
