Bad Blood by Neil Sedaka
Not a hit in the UK, but a big No. 1 in the U.S.
Lyrics to Bad Blood
Island Girl by Elton John
Elton stayed at No. 1 again with this great single from his album "Rock of the Westies".
Amazingly the lyrics are about a man trying to take a prostitute (could even be a gay prostitute) back to Jamaica. Elton himself did not "come out" until many years later.
