As if the air of expectation surrounding Bruce Springsteen's Glastonbury headlining set with the E-Street Band at the Pyramid Stage on Saturday wasn't enough, the Boss decided to help out some fellow New Jerseyans in the afternoon.

The Gaslight Anthem – the New Brunswick band whose second album 'The '59 Sound' is regarded as having more than a little chip off the old Boss block – joined up with the band to roar through the record's title track.

"Can you hear that sound? I'm feeling waves from home," singer Brian Fallon said – before the crowd at the John Peel Tent were greeted with the sight of Springsteen striding, guitar in hand, shades in place, onto the stage.

Their one-song collaboration over, Springsteen left smiling and Fallon said to the crowd: "You've been good to us and that is our present to you."

We at Spinner Towers believe it may be some time before the Gaslight Anthem are capable of doing anything other than grinning aimlessly.
