The BBC still celebrates Eurovision this May, despite a contest in Rotterdam no longer taking place.

This weekend, there's another chance to hear Nicki Chapman's Let's ABBA Party, a two-hour tribute to ABBA featuring some of the group's biggest hits, as well as a selection of covers, cast recordings and film soundtracks, plus a specially commissioned UK chart rundown of the group's eight studio albums - from Waterloo to The Visitors.

To mark the big occasion, have a go at Radio 2's ultimate ABBA quiz, featuring 50 questions that only the most fanatical Super Troupers will be able to answer.
