The covers band, named Big Shot, were performing at the Paramount in Long Island, New York when midway through the gig the real Piano Man star hit the stage for a three-song session.

According to Newsday.com, Joel performed covers of The Beatles’ With a Little Help From My Friends and the Rolling Stones' classic Honky Tonk Women before singing his track You May Be Right, which was mashed together with Led Zeppelin's Rock and Roll.

Joel, who was accompanied to the venue by his wife Alexis Roderick, also told the audience, "I only live down the road from here.”

The covers band, led by Michael DelGuidice, are all from Joel’s touring unit. After the Joel left the stage, Michael joked, “Was that a treat?... It took me six songs to realise what was happening.”

Meanwhile, Joel has announced he'll be joining New York Governor Andrew Cuomo on a statewide bike ride to raise awareness about breast cancer. The singer/songwriter will strap on his helmet for the day-long charity trek, which begins in Long Island on Monday morning (27Jun16).

At the conclusion of the event, Cuomo will be signing legislation that expands access to screenings for the disease in New York state.

The Governor, his girlfriend Sandra Lee - a breast cancer survivor - and Joel will join hundreds of motorcycle enthusiasts for the ride into New York City.

Harley Davidson bosses are donating a custom-made motorcycle for the Governor to ride. It will later be auctioned off to benefit the Breast Cancer Research Foundation.
