Bruce Springsteen had one last bit of familial duty before heading to the Southern Hemisphere for the start of the 'High Hopes' tour. He watched his son Sam officially became a New Jersey firefighter last week.

On Jan. 15, Springsteen's wife, Patti Scialfa, posted a photo of their 20-year son in his uniform on her Instagram account (officialrumbledoll, which is named after the title of her 1993 debut solo album). "My youngest son, Sam, graduated from Monmouth County Fire Academy tonight. #Proud #OurFamilyHero."

The Asbury Park Press reports that the Firefighter I class that Sam Springsteen took requires 188 hours of instruction on such topics as rescue, extinguishment, CPR, hazardous materials and equipment care.

“This is not an easy course -- there’s a lot of physical stuff and a lot of book work," said Monmouth County Fire Marshal Henry Stryker III, who added that Springsteen is "very smart. He enjoyed what he was doing.”

Sam Springsteen will be assigned to the fire department in his hometown of Colts Neck, N.J.
