ABBA's two leading men made a surprise appearance on stage as hit musical Mamma Mia! celebrated its 20th anniversary.
Benny Andersson and Bjorn Ulvaeus, one half of the Swedish pop sensation, delighted the audience as the ABBA-inspired show marked two decades in the West End.
The pair were greeted with huge applause and cheers from a packed Novello Theatre in London when they took to the stage after the show.
Ulvaeus thanked the "fantastic audience" and told them it was "both strange and wonderful to be on this stage tonight".
The ABBA stars, who wrote the music and lyrics to the musical, were joined by producer Judy Craymer, director Phyllida Lloyd and writer Catherine Johnson.

Andersson said backstage it had been "too long" since he had seen the show and that he felt moved on the anniversary.
The songwriter praised the cast as "wonderful" and added: "There is a chance to be immersed, to get moved, and I was tonight and I'm happy I can feel that."
Mamma Mia! is a feel-good tale centred around a mother, daughter and three possible fathers on an idyllic Greek island.
It unfolds to ABBA's timeless pop classics and has now been seen live on stage by 65 million people around the world.
Mamma Mia! was adapted for the silver screen in 2008 and starred Meryl Streep, Amanda Seyfried, Pierce Brosnan and Colin Firth.
