Per Gessle and ex-Abba Björn Ulvaeus have done a documentary on 70-year-old Swedish record producer Anders Burman. The documentary "Ulvaeus och Gessle i Burmans spår" will be shown on SVT1 on Christmas Day. The documentary is about Burman's career in music business and Per and Björn interview many of the stars Burman brought to the spotlight during the 50 years he was in the business. Per has never worked with Burman, but he has a refusal letter from Burman and his company Metronome framed on his wall. "I have one from Björn and Polar [the record company Abba established], too. Neither of them was interested in Gyllene Tider."
