Mario Bartolotti

The only performance that Roberto Marcocci could find with Mario Bartolotti was in January 1910 in Pisa at the Teatro Rossi as Alfredo in Traviata.
As only Bartolotti's name was known when the Sterling Cylinders catalog was discovered, the tenor "Bartolotta" listed in the catalog was thought to be a misprint. However new information has been found proving that there were two tenors: Bartolotti and Bartolotta.
