"Quattro cani" ("Four Dogs") and "Le storie di ieri" ("The Stories of Yesterday"). The latter, a song about the years of Fascism, had been already released on De André's 1974 album Volume 8, as it had been written during a stay in the Genoese singer's Sardinian estate. Bufalo Bill (1976) confirmed De Gregori's qualities, and contained at least two classics: the eponymous song and "Santa Lucia", the singer's own favourite. However, during a concert held in Milan in 1976, De Gregori, who had always declared his inclination to left-wing ideas and ideals, was fiercely contested by a group of extreme left agitators. In a mock "trial", they accused him of using a left-wing message solely to sell records and insisted that music should be free. De Gregori was at risk of injury in the fray, and decided to quit his musical career. During the following two years he therefore worked as a bookstore and music shop clerk. The episode, known as the "Palalido incident", influenced several works by other Italian singer-songwriters, such as Roberto Vecchioni's "Vaudeville".

In 1978, however, he returned with another inspired album, De Gregori, containing one of his most famous songs, "Generale". He declared that he felt this song much too important for him to continue staying away from the music world. The following year he joined his old friend Lucio Dalla with a highly successful live tour, entitled Banana Republic, and published a studio LP, Viva l'Italia featuring American musicians. The title track was later adopted as the Italian Socialist Party song, but De Gregori always opposed this choice. 1980s After a pause of several years, De Gregori returned with the album Titanic, the first part of which was like a concept album devoted to the famous episode of the sinking of the eponymous liner. The ballad "San Lorenzo", with a rare piano performance by De Gregori, concerns the dramatic episode of the bombing during World War II of the quarter in Rome by Allied planes. The freshness of the music and lyrics made this an outstanding commercial success, as well as earning the praise of critics. Titanic has been recently declared the best Italian LP of the period 1975–2005, in a
