'' 29 settembre '' was probably written in the autumn of 1966 . The song had a long gestation , and remained incomplete for a long time before it was actually finished . According to musicologist Salvatore Galeazzo Biamonte , '' 29 settembre '' was composed with the objective of overcoming the traditional pop song structure : In February 1967 , just after the end of Sanremo , Battisti resumed composing the song around Mogol 's lyrics and completed it . Battisti and Mogol then presented it to Mariano Detto , and asked him to come up with an arrangement
