If there’s a fire in Jersey City or a cat stuck in a tree, there’s a good chance that Bruce Springsteen’s son may be dispatched to the scene.

Sam Springsteen was one of 15 new firefighters who were sworn in Tuesday by Mayor Steven M. Fulop of Jersey City and the director of public safety, James Shea.

Bruce Springsteen, the rock star whose songs have for decades celebrated New Jersey’s working class, and Patti Scialfa, his wife and longtime bandmate, looked on and clapped as their youngest son joined the newest members of the city’s Fire Department, according to TV news coverage of the ceremony.

“It was a long road,” the senior Mr. Springsteen told WCBS at the ceremony held at City Hall. “He was very dedicated for quite a few years and we are just excited for him today.”
