"Hasta Mañana" (Spanish for "Until tomorrow") is the fourth track on Swedish pop group ABBA's second studio album, Waterloo. Initially fearing that "Waterloo" might be too risky to enter for the 1974 Eurovision Song Contest, the group considered performing the ballad "Hasta Mañana" instead, as they thought that it was more in style with previous Eurovision winners. Eventually, they decided on "Waterloo", primarily because it featured Agnetha Fältskog and Anni-Frid Lyngstad sharing lead vocals, whereas "Hasta Mañana" had Fältskog as the sole lead vocalist. ABBA believed that this would give the wrong impression of them to the world.
