here, the Dutch top40 chart celebrated its 50th birthday in January this year. When I posted about that event, I included my top50 songs that made the top40 chart in the past. I was intrigued how few of my favourite songs actually made the #1 position, so the rest of the year I will be posting at a rate of one a week (on Saturday, the day the top40 was broadcast) my countdown of fifty favourite #1 hits. At #37, we find an unlikely cooperation between Olivia Newton-John and the Electric Light orchestra (#1 in 1980). It is completely over the top, including the clip, and yet I love it. Art Rock score: 9/10 (awesome song, one of the 1000 best of all time).
