Blonde vocalist Marilyn Duke worked with Jolly Coburn’s orchestra in 1937 and joined Vaughn Monroe’s band in early 1941. She left Monroe in July 1943 and sang with Will Osborne before starting a ten-week solo appearance in Boston in June 1944. She was back with Monroe the following month however. In November of that year, she provided female vocals on Monroe’s number one hit “The Trolley Song,” the ﬁrst song recorded by Victor after the end of the American Federation of Musician’s recording ban. Duke was gone from Monroe’s orchestra soon after.
In September 1944, Duke married Boston amusement park owner Peter Brien. She also co-wrote the song “I’ll Love You Forever” with Teri Josefovits that same year. In the mid-1950s, she was singing in Las Vegas.
