They were most popular in the late 1960s, when they released a string of hit singles with the contribution of renowned lyric-writer Mogol and songwriter Lucio Battisti,[2][3] their greatest successes being "Sognando la California" and "Senza luce", respectively covers of "California Dreamin'" by the Mamas and Papas and "A Whiter Shade of Pale" by Procol Harum.
Their second single, Sognando la California, was released in October 1966 and ended up topping the Italian charts for two months.
[7] After a couple of relatively successful singles, such as Laser vivente (1980) and Giornale di bordo (1982), the band went on hiatus.
Pietruccio, Pepe, and Lallo eventually reconvened and released a few more singles such as L'amico mio (1983) and Senza luce... reggae (1984), and participated in the Musicaitalia per l'Etiopia humanitarian project for Ethiopia.
In 1993 they performed again at the Festival di Sanremo together with former rivals I Camaleonti, another band from the 1960s-1970s Italian scene, and Maurizio Vandelli from Equipe 84.
In 2021, they released their last studio album "Una vita d'avventura" (An adventurous life) which contains six new songs and new recordings of five of the band's evergreen.
