I was browsing through some YouTube videos of 80s music and this song kept coming up as a recommendation. I don’t remember hearing this song at all back in the day, so I took a listen.
If you know 80s pop music, try listening to this video with your eyes closed. Ignore the lyrics and I’m pretty sure you’ll hear “I Heard A Rumour” by Bananarama.
A quick peek at Wikipedia confirmed my suspicions.
