Here's something that definitely won't require any sort of apology from John Mayer.
While performing, John took notice of 11-year-old Austin Christy holding up a sign that read "Can I play 'Belief' with you?" reports CourierPostOnline.com. He graciously invited the sixth-grader up on stage, where the two jammed together for the crowd of roughly 25,000 fans, including Austin's mom.
As if that weren't enough, John even gave the kid an autographed guitar as a parting gift.
