Rock 'n roll and Jersey legend Springsteen is still going strong, even past his 60th birthday.

At the "Stand Up For Heroes" benefit Wednesday night, a New York Comedy Festival charity event produced with journo hero Bob Woodruff to benefit injured American troops, Bruce Springsteen told a knock-knock joke and then auctioned off a Harley.

If the new Bruce Springsteen track "Your Own Worst Enemy" isn't the perfect cover song for Stephin Merritt of the Magnetic Fields—if not being an actual tribute—we'll eat Clarence Clemons' sweaty hat. Also "Girls In Their Summer Clothes."

Is Bruce Springsteen having an affair? Page Six seems to think so, alleging that the singer and his wife Patti Scialfa are living separate lives. Springteen, the Post tells us, "is born to run - from marriage."
