Like a Boss: Springsteen brings birthday boy on stage to sing

The lesson? Always bring a sign saying it's your birthday. Everywhere.

One lucky birthday boy got to rock out with Bruce Springsteen at his Thomond Park concert last night.

The Boss spotted a sign in the crowd announcing it was someone's birthday, and while he was down at the barrier, decided to pull the lad up for a tune - Waitin' on a Sunny Day.
