He added: "My case was the United States of America vs Bruce Springsteen. That's always comforting to hear — the entire nation is aligned against you."
Elsewhere during the show, Bruce spoke movingly about his mom, Adele Springsteen, and her battle with Alzheimer's disease.
He said: "She can't speak. She can't stand, but when she sees me there's a smile and there's still a kiss and there's a sound she makes and I know it means I love you.
"When I put on Glenn Miller she starts moving in her chair, reaching out for me to take her in my arms once more and dance. I love her."
And the singer admitted being back on Broadway helped him feel closer to his late father Douglas, who died in 1998.
He said: "I'm glad to be doing this show again this summer because I get to visit with my dad every night that I'm here. It's a lovely thing."
