"Waterloo" is the first single from the Swedish pop group ABBA's second album of the same name, and their first under the Atlantic label in the US. This was also the first single to be credited to the group performing under the name ABBA.

The Swedish version of the single was backed with the Swedish version of "Honey, Honey", while the English version featured "Watch Out" on the B-side.

ABBA kind of stumbled their way into Voyage, their first album in 40 years. In 2016, the group began working on ABBAtars, a virtual concert based on the band's blockbuster 1979 tour and featuring 3D renditions of Benny Andersson, Björn Ulvaeus, Agnetha Fältskog, and Anni-Frid Lyngstad.

They became one of the most commercially successful acts in the history of popular music, topping the charts worldwide from 1974 to 1983. In 1974 ABBA were Sweden's first winner of the Eurovision Song Contest, with the song "Waterloo", which in 2005 was chosen as the best song in the competition's history as part of the 50th anniversary celebration of the contest…

Abba, from winning the Eurovision Song Contest in 1974 were to become one of the most popular groups of all time. Carl Davis saw the performance that night and admired the cleverness of the arrangement, the composition, and the sheer cheekiness of their presentation. Forty years later, their music lives on and he decided, having taken soundings from colleagues and industry representatives, to make an Abba for Orchestra album, having already successfully made Beatles for Orchestra and Bond for Orchestra albums.
