The group recorded a Spanish version of the song, written by them, Rowe, Stannard, and N. Maño. The title was "2 Become 1" (Spanish Version), although the title is loosely translated in one line of the song, "Seremos Uno Los Dos". It was released as the eleventh track of their debut album "Spice", in Latin America, South Africa, in a special re-edition of the album in Spain, and as one of the tracks of the "2 Become 1" maxi-single in the US.
