Country star Zac Brown got a taste of Fenway Park magic ahead of his Friday and Saturday night (27-28Jun14) concerts at the Massachusetts baseball Mecca by joining Billy Joel onstage in Boston on Thursday (26Jun14).

The Uptown Girl hitmaker introduced Brown onstage towards the end of his stadium show for a rendition of You May Be Right.

Brown hit the stage as Joel said, "I'm playing one night at Fenway Park, but this guy is playing two."

The country star is a life-long fan of Joel and the Zac Brown Band have been known to cover his Piano Man hit at gigs. It is not known if Joel will return the favour and hit the stage with Brown.
