Recently I have discovered two videos with historical recordings from a 78 record by the group Bonetti Brothers Melody Makers with mandolin.
The Mandolin Serenade has been composed by Dario C. Bonetti. I have found some information about Dario C. Bonetti in the archive of the University of Iowa Traveling Culture: Circuit Chautauqua in the Twentieth Century. Chautauquas were very popular until the end of the 1920s when the movie business changed the situation and Chautauquas became less popular.
The flyer about Dario C. Bonetti stems from a later time, after World War II. Here are two quotes from this flyer:
Dario C. Bonetti, who was one (of) Italians formost plectrum guitarists, ranks with the world’s great guitarists. He now is an American citizen and will make his first American concert tour with a special electric guitar under Redpath management.
Dario Bonetti was a seargeant-musician in World War II and entertained in Europe with Joshua Logan, Mickey Rooney, Bobby Breen, Red Buttons and Eugene List.
The flyer can be found on the following page:
I have not found other information about the Bonetti Brothers or about the mandolin which has been used on the recording. I have found some information about the history of the Okeh label, and for me it looks like this record has been made around 1945.
This is my playlist with the two pieces:
Mandolin Serenade (Dario C. Bonetti) + Love Melody (V. Cesarino)
