After distressing experiences including a devastating auto accident and performing unsuccessfully in a play in Los Angeles, in 1946 Bartholomew married publicist Maely Daniele. Daniele, six years his senior, was a twice-divorced woman, and his marriage to her caused a serious and permanent rift with his aunt, who moved back to England. The marriage was not a happy one.
In 1946 he was in a radio play in an episode of Inner Sanctum Mystery. In 1947, he appeared as himself in a five-minute cameo in the otherwise all-black musical film Sepia Cinderella, relating his post-war efforts to have a successful vaudeville routine and telling a few gags onscreen. He spent most of 1948 touring small American theaters, and in November 1948 left without his wife for an Australian tour as a night-club singing, patter, and piano act.
