Fascination Valse Lento composed by Dante Marchetti arranged for accordion solo by Anthony Galla-Rini.
Fascination Valse Lento is not by Filippo Marchetti (1831–1902) — the Italian opera composer known for Ruy Blas and Romeo e Giulietta. The piece you’re asking about was actually composed by Fermo Dante (Dante Pilade) Marchetti (1876–1940), a completely different composer. The similarity of names causes frequent confusion in catalogues and online references.
