HERE IS SOME DETAILS OF HIS WORK FROM
"ITALIAN TIMES":
Nero Fidicen – Una Commedia in Latino
The writer/director was Dan Lundberg, a former CBS foreign correspondent and creator/publisher of the influential Lundberg Letter. Bill Conti (or “William Conti,” as he’s billed here) was at that time studying music in Rome. He wrote two songs for the album – “Mundus, Eras Amabilis” (“World, You Were So Lovely”) and “O Uxor Vilis” (“Oh, Worthless Wife”), composed the underscoring and transitional themes, and conducted the seven-member ensemble and also The Lower Via Veneto Chanting and Choral Society. Bill Conti’s wife, Shelby Cox Conti, was responsible for Choreographic Effects. (Thanks very much for this info to Stuart Cleland)
