He entered the Army in 1953 and served at Camp Polk (now Fort Polk) in Louisiana. His admiration for Sinatra’s music swelled when he listened to his records on the radio at night in the barracks. “Somehow his voice got to me and I realized he knew exactly what he was singing about,” he told Vice. “If he was singing about lonely, he knew what lonely was. If he was singing about love, he knew what love was about.”
Mr. Mark stopped using his surname early in his career but never changed it legally.
After his discharge in 1955, Mr. Mark got a job at the Red Hill Inn, a jazz club in Pennsauken, N.J., as a talent coordinator. His responsibilities included driving artists like Count Basie and Duke Ellington to and from their hotels. They would often talk about Sinatra, further stoking Mr. Mark’s interest in his music. More important, he was hired around that time as a disc jockey at WHAT-AM, a jazz station in Philadelphia. He hosted a one-hour show called “Sounds in the Night.”
One night in 1955, when the station’s overnight D.J. did not show up, Mr. Mark was asked to fill in.
“It was a show called ‘Rock and Roll Kingdom,’ and I wasn’t going to do that,” he told The New Yorker in 2021. He asked his audience what they wanted to hear, and one fan suggested playing an hour of Sinatra’s music. “The all-night guy got fired for not coming in, and they kept me on.” Several months later, in 1956, the show formally began its run as “Friday With Frank.”
By the early 1960s, Mr. Mark’s popularity in Philadelphia was growing. He was hosting “Friday With Frank” and a daily six-hour jazz show, “Mark of Jazz,” which would run for nearly two decades, on WHAT. He also had a weekly jazz program on local public television.
