With lyrics by Giuseppe Fiorelli and music by Mario Ruccione, including live guitar accompaniment provided by Piero Gozo, the song holds the distinction of being the longest song in Contest history. Writer John Kennedy O'Connor describes it as "over five minutes long" in his work on the Contest, and Des Mangan records it as "5 minutes and 9 seconds", as well as suggesting that the listener "would have thought of many better uses for the strings of his guitar". Following this Contest, the rule governing the length of entries was tightened to require them to be no longer than 3.5 minutes initially and later 3 minutes exactly, with both authors agreeing that the change was due to this entry's length. In the 2007 edition of John Kennedy O'Connor's The Eurovision Song Contest - The Official History, the song is officially listed as the longest entry in the history of the contest, ironically being performed after the officially listed shortest song. 
The song itself is a ballad in the chanson style popular in the early years of the Contest. Gallo sings of his mixed feelings at seeing a former lover and realising that she is no longer interested in him. He asks the strings of his guitar to play for him alone, since she has no interest in their music anymore.
