In a nod to the Mamma Mia! The Party Teaser in 2015, Björn once again  uses paint to indicate and celebrate the 10th Anniversary of the Swedish Mamma Mia! The Party.

In a social media post, he said, “Mamma Mia! The Party started as an experiment, the format had not been tried before. Never could I have imagined that the audience would love it so much! 10 years, that's wonderful! ” 

The party will continue in Spring 2026 and the tickets for the Gala Night and the new season will be released on 24 October 2025. 

On 21 October 2025, a behind-the-scenes short video reel was published by Happytear, the company behind the video of Björn painting onto the glass - the client being Pop House Entertainment.  The video showed Björn learning how to ‘fling’ his arm with a paintbrush in hand and also showed him signing a white electric guitar for reasons that might become clear in the coming days/weeks.
