Though his early singles with Brasil '66 (most notably "Mas que Nada") met with some success, Mendes really burst into mainstream prominence when he performed the Oscar-nominated "The Look of Love" on the Academy Awards telecast in April 1968. Brasil '66's version of the song quickly shot into the top 10, peaking at No. 4 and eclipsing Dusty Springfield's version from the soundtrack of the movie "Casino Royale". Mendes spent the rest of 1968 enjoying consecutive top 10 and top 20 hits with his follow-up singles "The Fool on the Hill" and "Scarborough Fair". From 1968 on, Mendes was arguably the biggest Brazilian star in the world and enjoyed immense popularity worldwide, performing in venues as varied as stadium arenas and the White House, where he gave concerts for presidents Lyndon B. Johnson and Richard Nixon. The Brasil '66 group appeared at the World Expo in Osaka, Japan in June 1970.
