There's a guitar part in this Eno/Byrne song which is very similar to the famous motif in How Soon Is Now? It first appears at 1 minute 11 seconds. I'm not saying Marr nicked it or anything. The song just came on randomly on my computer and struck me as being very similar and, well, I'm bored innit and thought I might waste some people's precious seconds with this non-revelation.
