Nice to do a quiz that isn't based on the U.S. charts, but only 4 minutes? I'm not the fastest typist and was nowhere near finishing. (got 43 though) :^)
Fair point but it remained in the charts into 1980 and a re-recorded version was a UK hit in 1987. It is generally linked with the 80s, just happened to be recorded 4 months before.
You might want to allow Yaz for Yazoo, as they were known as Yaz here in the US.
