Detroit native Rosemary Calvin sang and recorded for Vaughn Monroe in early 1945 before joining George Paxton in August of that year. In early 1947, she worked with Les Elgart, also signing with the Majestic label and releasing two sides with the Tony Mottolo Four.
By late 1948, Calvin was back with Paxton. When the bandleader scrapped his orchestra in early 1949 to open a music publishing house, she joined fellow ex-Paxton singer and trumpet player Johnny Bond as vocalist for his new ﬁve-piece orchestra. The group recorded on the MGM label. She often received co-billing with Bond and remained with the band until at least late 1951.
