was recorded at Château d'Hérouville, near Paris. This album is generally considered the best album of his career. In 1972, he released the album Eu Vou Ser Como a Toupeira ("I Will Be Just Like The Mole"), recorded in Madrid at the Cellada Studios. In 1973, José Afonso continued his "pilgrimage", singing all over Portugal. Many of his appearances were forcibly cancelled by the PIDE/DGS. In April he was arrested and sentenced to 20 days in the Caxias prison (a facility used mostly to jail political prisoners). In the prison he wrote the poem Era Um Redondo Vocábulo. For Christmas, he released the album Venham Mais Cinco ("Let Five More Come"), recorded in Paris and on which José Mário Branco collaborated. Janine de Waleyne from the Blue Stars of France, a prominent vocalist in French chanson, guested on the title track. On 29 March 1974, Afonso participated in a concert event at the Coliseu dos Recreios in Lisbon, called "First Meeting of the Portuguese Song" (Portuguese: Primeiro Encontro da Canção Portuguesa). This was an event sponsored by Casa da Imprensa in which several folk singer-songwriters and musicians with anti-Estado Novo inclinations participated. The state censorship still operated in the event, and Afonso was forbidden from performing some of his songs with more political messages, such as "Venham Mais Cinco" and "A Morte Saiu à Rua". "Grândola, Vila Morena", however, was not seen as a subversive song and was allowed to be performed. Almost one month later, on 25 April 1974, the Portuguese Estado Novo regime was overthrown in a nearly bloodless military coup, known as the Carnation Revolution. "Grândola, Vila Morena" was one of the two songs used as a radio-broadcast signal by the Portuguese Armed Forces Movement during their coup operation and is considered ever since the anthem of the revolution. 1974–1980: Revolutionary period In December 1974, Afonso released the album Coro dos Tribunais ("Courthouse Chorus"), which was recorded in London, again at the Pye Studios, with musical arrangements by Fausto Bordalo Dias. The album includes two Brechtian songs, composed in Mozambique in the period between 1964 and 1967: "Coro dos Tribunais" and "Eu Marchava de Dia e de Noite". From 1974 to 1975 he became directly involved in the popular revolutionary movements. The PREC (Ongoing Revolutionary Process) became his passion. He performed on 11 March 1975 (the day of a failed coup led by António de Spínola) in
