 According to Bubola, both sides of the single feature unspecified members of Premiata Forneria Marconi and New Trolls, in what the songwriter referred to as "a sort of jam session".Later on, during a TV interview to promote New Trolls' 2013 album "Concerto Grosso N° 3", where the then-current band was billed as "La Leggenda New Trolls" due to an ongoing lawsuit involving former guitarist Ricky Belloni, founding member Vittorio De Scalzi (a longtime friend of De André's, who frequently includes songs by his fellow Genoan musician into his own stage act), tentatively remembered the line-up for "Una storia sbagliata" as being made up of himself on piano and keyboards, with PFM's Franz Di Cioccio on drums, Patrick Djivas on bass, and Franco Mussida on guitar.Belloni and Bubola also played guitars and the latter sang a higher-third harmony to De André.
