Kenny Chesney sure had a fun weekend in Pittsburgh. In addition to headlining his own massive concert on Saturday (July 2), he joined the legendary Billy Joel onstage during Joel's Pittsburgh gig on Friday (June 1) to perform "You May Be Right."

The country superstar pays comical tribute to Joel as he takes the stage at PNC Park in the video above, giving an air-bow and crying out to the audience, "We're not worthy!" in full-on Wayne's World style before Joel's band kicks into the song.

Clad fairly casually in a ball cap and T-shirt, Chesney strides around the stage and nods along to the classic song as Joel begins the first verse, then takes the lead on the second part of the verse as the stadium crowd goes crazy. The two megastars blend their voices together on the all-time classic chorus: "You may be right / I may be crazy / Oh, but it just may be a lunatic you're looking for."

In another big surprise, at the end of the song, as the band rides the outro and Joel and Chesney chant, "You may be wrong but you may be right," the song segues unexpectedly into Led Zeppelin's "Rock and Roll," with one of Joel's band members stepping up to the mic to deliver his best Robert Plant impression for one time through the verse before they transition back into "You May Be Right," handing it back over to the all-star pair to bring the song home.

Chesney and his band took the stage at Heinz Field the following night for a headlining show that drew more than 47,000 people.
