Their first record and most popular song Un Ragazzo di Strada was a rewriting of I Ain't No Miracle Worker by the Brogues. In 1966, the group followed up with a version of Bang, Bang and on the flip side, Che Notte Ragazzi! from the film of the same name directed by Giorgio Capitani. In late 1966, the band released their first album which included two covers of Donovan songs: Colours and To Try For The Sun. In 1967, they released Sospesa ad un Filo, a cover of I Had Too Much to Dream Last Night by the Electric Prunes and Bambolina a cover of Any Day Now by Burt Bacharach. In 1968, they changed label and released Datemi un Biglietto Di Aereo, a cover of The Letter by the Box Tops and Questo E' Giusto a cover of Morning Dew by the Episode Six.
In 1969, co-founder of the band Fabrizio "Billo" Levati left the group and began a successful 30-year career as a club and radio-DJ.
