In 1976, ABBA were expanding in all directions, and exactly 40 years ago, on the Billboard Hot 100 for 22 May, ‘Mamma Mia’ made its chart debut at No. 83.

In a twist ending straight out of a movie, "The Equalizer 2" shot past "Mamma Mia! Here We Go Again' to steal the box office crown.

The summer smash "Mamma Mia!" logged a third consecutive weekend atop the international box office as its total raced to $334 million.
