Beginning in 1945, Sgalambro worked jointly with the review magazine Prisma (directed by Leonardo Grassi); his first writing was Paralipomeni all'irrazionalismo.

Sgalambro's role included managing pamphlets, publishing a pair of works (Dialogo sul comunismo and Contro la musica), and printing some operas by Giulio Cesare Vanini and Julien Benda.

Starting in 1998 he penned song lyrics for Patty Pravo (Emma), Fiorella Mannoia (Il movimento del dare), Carmen Consoli (Marie ti amiamo) and Milva (Non conosco nessun Patrizio).

In 2001, he published the album Fun Club, produced by Franco Battiato and Saro Cosentino, containing songs including La vie en rose (by Édith Piaf), Moon River (by Henry Mancini) and Me Gustas Tú (by Manu Chao).

In 2009, he published the single La canzone della galassia, containing a cover of Galaxy Song (taken from Monty Python's The Meaning of Life), sung with the Sardinian-English group Mab.
