Mamma Mia! has some of movie musical’s most iconic songs, but audiences have wondered if they were really sung by the stars, including Meryl Streep and Amanda Seyfried. Mamma Mia‘s heartwarming story has entertained fans for years since its theatrical debut in 2008, partly due to Streep’s status as an entertainment triple threat. Seyfried’s performance adds to the film’s appeal, carrying both the story and the music throughout the years.

Mamma Mia!’s music, written by Swedish pop group ABBA, gave it a unique musical tone that carried over from its original Broadway show. Though Mamma Mia 3 updates are few and far between, that tone has stood the test of time, keeping the films in the public consciousness. One reason it has been able to is that the entire cast of the film was so game to do the movie, including Streep and Seyfried, enhancing every performance as the story was carried to the silver screen.
