Paul Baron led studio orchestras during the 1940s and 1950s, conducting for such artists as Mildred Bailey, Perry Como, and Mario Lanza, as well as recording under his own name. He was also featured on his own CBS radio program during the war years.
Baron also allegedly co-wrote, with Jerri Sullavan and Maurey Amsterdam, the Andrews Sisters' calypso hit ''Rum and Coca-Cola.'' The song sparked a famous lawsuit against Baron and Sullavan by West Indies composer Lionel Belasco, who accused them of copying the melody of his song ''L'Annee Passee.'' The court ruled in Belasco's favor, though Baron, Sullivan, and Amsterdam still bear official status as the song's composer. The lyrics to ''Rum and Coca-Cola'' were found to have originally been written by calypso artist Rupert Grant.
