Some of the side jobs he had were playing violin in a theater-pit orchestra, working at a meat-packing plant, serving as a movie-house usher, tinsmith, freight-elevator operator, restaurant cashier, and porter at a bindery. At age 16, he was watching vaudeville, of which he had been a fan since the age of 10, and he witnessed Jack Osterman singing a ballad Osterman had written. Cahn was inspired and, on his way home from the theater, wrote his first lyric, which was titled "Like Niagara Falls, I'm Falling for You – Baby." Years later he would say "I think a sense of vaudeville is very strong in anything I do, anything I write. They even call it 'a vaudeville finish,' and it comes through in many of my songs. Just sing the end of 'All the Way' or 'Three Coins in the Fountain'—'Make it mine, make it mine, MAKE IT MINE!' If you let people know they should applaud, they will applaud."
