During a performance in Connecticut, Springsteen, who is known as 'the Boss' shouted "This one's for Preet Bharara" before singing 'Death to My Hometown,' a composition about the effects of the economic crisis.
A huge fan of Springsteen, Bharara was sitting in the audience at the concert with his young son.
"All I could think was, my son for the first time thought his dad was really cool," the New York Daily News quoted Bharara as saying.
The Springsteen shout-out came a day after Bharara's office recorded another victory in the crackdown against insider trading on Wall Street with former Goldman Sachs director Rajat Gupta getting a two-year prison term.
Bharara has been to 25 Springsteen concerts over the last decade.
Bharara said he could not share any other memory of the concert as "it's all a blur to me because I lost all my memory when he said my name."
Meanwhile, Bharara, who had no power at his home in Westchester County in the wake of the storm Sandy extended his sympathy to the storm's victims.
"In the wake of such devastation, it's heartening to see people come together to, as Bruce would say, take care of our own," Bharara said. "That's what good people always do."
