We were approached by Britannia English Course to increase the presence of the brand in private schools in Rio de Janeiro. The idea was renting a "double decker" bus, tacked it to look like a traditional London bus, and there he went through Rio's Southern Zone announcing the action. The bus parked in front of the schools at the time students left. We set up a London-style telephone booth, where participants chose English songs and sang like a karaoke - recorded and posted on the action hotsite. We also made a partnership with Radio Mix for promotional support: every time the bus went to a school, Radio announced on the air, which guaranteed more participants.
