A recently divorced woman (quite a scandal in the sixties) singing about how she feels being addicted to the attention of her lover. Like a puppet on a string she is waiting for his every call. Sing Sandie Shaw didn’t like it, but it got elected as the song for England in the Eurovision Song Contest for the year 1967 just the same.
And it won the first English victory, and took Europe in a storm. In the years after, it was covered in 30 languages all over the world, including Finnish, Mandarin and Tamil. Not bad for a piece of sexist drivel on a simple cuckoo-clock tune.
