LONDON - Commentary by Per and Marie is included in a documentary about the members of ABBA produced for BBC radio in the U.K.

  The program attempts to reveal the secrets of the Benny Anderson and Björn Ulvaeus songwriting partnership, one of the most successful in the history of pop. While various ABBA releases still sell around 3,000 copies worldwide per day, Benny and Björn have gone on to write for the stage. "Mamma Mia!", a musical based around ABBA songs, is a current smash hit in London, Toronto, and New York.

  The program airs on BBC Radio 2 beginning on Tuesday, January 8th.
