Björn Ulvaeus (Music and Lyrics) was born in 1945 in Gothenberg on the west coast of Sweden. After a successful local career in Sweden with a folk group in the mid 1960s, he started his collaboration with Benny Andersson. They then went on to form ABBA with Agnetha Faltskog and Anni-Frid Lyngstad. Even during the ABBA years, the idea of writing a musical seemed appealing and, in 1981, Björn and Benny met Tim Rice and co-wrote Chess with him, which opened in the West End in 1986. In 1995 Björn and Benny opened a new musical called Kristina Från Duvemåla, which played for three years in Sweden. Their most recent musical is the Stockholm production Hjälp sökes, which opened in 2013. Bjorn is one of the producers for MAMMA MIA! The Party, which opened in Stockholm in January 2016.
