In 1950, as an established act, Dean and Jerry broke their own attendance record at New York's famed Copacabana. When they first played the club in 1946, they received second billing to Vivian Blane - a big star in Hollywood and on Broadway at the time. In Dean and Me, Jerry reports that the billing arrangement lasted only that first night. After that, she opened for them - and they became headliners wherever they played.
