Bruce Springsteen continues to do some awfully cool things on stage as he tours Europe this summer. This latest act of 'coolness' happened in Ireland last week, when the Boss took six year old Sophie Sutton from her dad's shoulders, and pulled her on stage to sing with him in front of 35,000 concert goers. Turns out, she knew the words to 'Waitin' On A Sunny Day', and might have even upstaged Bruce! Watch for yourself after the jump!
