Portugal was represented in the Eurovision Song Contest 2005 by the song "Amar", (To Love) performed by 2B. It was selected internally by RTP (Portugal). The Portuguese National Final was broadcast on March 31 during a televised show called Gala de Aniversário RTP. The song was written by Alexandre Honrado, Ernesto Leite and José da Ponte and composed by Ernesto Leite and José da Ponte. It is one of few uptempo Portuguese entries in the Eurovision Song Contest.
2B was created only for the purpose of representing Portugal at the 2005 Eurovision Song Contest. The group consists of Luciana Abreu and Rui Drumond who both gained their fame through talent competitions. Luciana competed in the TV song contest 'Ídolos' ('Pop Idol') in 2003, while in the same year Rui took part in the TV series Operação Triunfo, broadcast by RTP. Both take part in various stage plays and theatre productions.
2B performed at the semi-final in Kiev with reasonable hopes for qualifying for the final. Unfortunately, a faulty microphone for the female singer and overall technical mishaps resulted in a disastrous performance. As a result, the song did not qualify, finishing 17th in the semi-final.
Even though one of the EBU rules state that songs can be performed again if the first performance is hindered by technical faults, the song was not repeated.
The spokesperson who revealed Portugal's votes for other countries was RTP host Isabel Angelino.
