ABBA’s career was at a pivotal moment during the time of their live recording of "Waterloo." Prior to the live performance, ABBA had released their self-titled album "ABBA" in 1975, which included the hit single "Mamma Mia." The act of performing "Waterloo" live on a prominent platform such as "America’s Got Talent" underscores the song's lasting influence, as "Waterloo" was ABBA's breakthrough hit that won the Eurovision Song Contest in 1974. This victory not only propelled ABBA into international stardom but also marked the beginning of their prolific output of pop music that dominated the charts throughout the 1970s. The live rendition by Cher connects the legacy of ABBA's music with its continued relevance in contemporary pop culture, showcasing how their songs have transcended generations and remain beloved classics.
