The musical "Mamma Mia!" − composed by Ulvaeus and Andersson and based on their songs − has since its first opening in 1999 been seen by over 70 million people around the world, according to its creators. It has also led to two blockbuster movies.

Ulvaeus told Swedish TV4 after the ceremony he felt "very emotional" receiving the order, especially since it originated from the Swedish public.

Sweden has four orders of chivalry, established in the 18th century, of which the Vasa Order is the most junior.

Members of the public propose recipients and the formal decisions are made by the government.
