Björn made a guest appearance on this Saturday night family comedy show.

An amusing teaser appeared on Twitter a few days beforehand the broadcast showing Björn drawing a (very good!) sketch of Michael McIntyre.

The actual TV show had Björn judging a section called "ABBAoake" where four people had been secretly filmed singing ABBA songs at Karaoke bars in Cardiff and Liverpool and then surprised in the audience with the footage - and Björn judging them.

To ensure a mention of Mamma Mia! The Party was included, two singers from The Party were also on stage with Björn.

He got a great reception from the audience who gave him a standing ovation as he walked on stage.  Björn seemed to have a lot of fun.

Other guests on the show were Bear Grylls and Liam Payne.

YouTube continually block attempts to upload the programme but they have their own short clip which gives a flavour of the show.
