After the great celebration of 40 years of songs - with concerts at the Meo Arena, Super Bock Arena, Multiusos de Guimarães, Rock in Rio, Vilar de Mouros and an extensive tour of festivals and parties from the north to the south of Portugal - the Delfins, like monks of their own destiny, return to the intimacy of theatres and auditoriums for a unique tour, where many of the songs that are usually left out of playlists are given a new lease of life.
