Nucha's first participation in Portugal's Eurovision selection, "Festival da Canção", was in 1988 with the song "Se calhar", but this failed to pass the semi-final stage. She entered "Festival da Canção" a second time in 1990, and this time was successful with the song "Há sempre alguém" ("There's Always Someone") winning the juries' vote. "Há sempre alguém" went forward to the 35th Eurovision Song Contest, held on 5 May in Zagreb, where it did not prove popular, finishing in 20th place of the 22 entries, having received points only from the Luxembourg and United Kingdom juries. However, the song did prove to be popular in Portugal.
