Also appearing on TV talent show Opportunity Knocks, Lena Zavaroni holds the title of youngest person to have a top ten album in the UK charts. At just ten years old, Lena released the snappily titled Ma!! He's Making Eyes At Me and reached number eight in the UK charts. Zena also holds the record for the youngest person to appear on the BBC's Top of the Pops. Phew! That's a lot of work for a ten year-old!
