In 1973, the Maessens moved to Belgium, where they became in-demand backing vocalists. Bianca had married a Belgian singer, Luc Smets, and the four decided to form a group called Dream Express, enjoying immediate success with a single, also called "Dream Express", which reached No. 2 on the Flemish chart in 1976. In 1977, Dream Express entered, and won, the Belgian Eurovision selection with the song "A Million in One, Two, Three". Sung in English, it was a very contemporary track which was widely regarded as one of the favourites for that year's Eurovision, held in London on 7 May. Its seventh-place finish of 17 entrants was therefore considered something of a disappointment. Patricia left Dream Express soon afterwards, and the others carried on as LBS before disbanding in 1981.
