Star gives Austin Christy signed instrument
John Mayer surprised a fan at a gig by inviting him on stage to perform.
The singer noticed Austin Christy, 11, holding up a sign that read: ‘Can I play Belief with you?’
So John, 32, gave him a guitar and they jammed in front of the 25,000-strong crowd in Philadelphia.
He even signed the instrument and gave it to Austin as a parting gift.
