There is no such thing as "Tosca a Puccini Vordi Mozart Rossin",
but Puccini wrote an opera called Tosca; and Verdi, Mozart and
Rossini were composers.

The opera was first performed in 1902 and its composer, Cilea,
used the style of verismo that Puccini is known for. This was after
the death of Verdi. So it's possible but not something competent
analysts have found.
