In a letter sent to record label EMI with album notes, Russo said that the track was "until now unbeatable as the last track of the first side and too dense for extensive airplay. Many believe, however, that it is the strongest track of the album and, consequently, an instant hit single. But it is not the track to be worked at the start. The conception originally included a final acoustic sequence that would be an impromptu (acoustic guitar, wind, campfire, waves, effects) commenting on the theme and the ideas presented by the song itself and preparing the terrain for the second part of the work, side 2."{{sfn|Alexandre|2013|p=284-285}}
