The call included an invitation to form a choir of diverse ages and backgrounds to sing the song of the Educating City, as well as a poem by Ramon Fernàndez Jurado, former City Councillor of Castelldefels, which defined the Educating City before it was even talked about. More than 70 singers and musicians gathered in the the municipality’s central square.

It is worth noting the promotion of this initiative by Mª Josep Udina, a member of the La Finestra Association and author of the lyrics of the song.
