This weekend back in 1988, our own Rick Astley went to number one in the USA for the 2nd time!

He was riding high with Together Forever - a song that didn't top the charts in the UK.

So, this week on High School Days, listen out for more songs like that - big back home in the UK, but even bigger in the USA.

And there were plenty of them...See how many you can remember with our fun HSD Homework.

Good luck!
