Ulvaeus was born in Gothenburg, Sweden, but as a child he moved with his family to VÃ¤stervik. After being a member of ABBA he has, together with Benny Andersson, created the musicals Chess, Kristina frÃ¥n DuvemÃ¥la (based on the Immigrant novels by Swedish writer Vilhelm Moberg), and Mamma Mia! (based on existing ABBA songs).

In 1979, BjÃ¶rn and Agnetha divorced, although they both agreed to remain in ABBA. BjÃ¶rn later married Lena KallersjÃ¶ on January 6, 1981, and the marriage produced another two daughters.
