De Wolfe maintained that "Girl in the Dark", the work of Dutch composer Jan Stoeckart in 1960, had been submitted to other people before the copyright was assigned to them in 1966 (i.e. including a period before "Sogno Nostalgico" had been composed). A settlement was reached in 1975 once it became clear – from the 1974 feature film – that "Callan" was no longer using the piece, so that royalties had dried up. Copyright in it was vested by agreement in Mood Music in 1975, together with future royalties (but "Callan" never used it again), with De Wolfe retaining the majority of the royalties earned up to that point.
