Billy Joel announced he'll be pushing his Fenway park concert -- originally set for this August 28th -- for next year. Pending final approval by the City of Boston, the make-up date for the gig will be August 4th, 2021.

A message to fans was posted on BillyJoel.com, which read, "Tickets purchased for the 2020 concert will be honored for the rescheduled date. Ticket holders will be emailed directly with refund options for those unable to attend next year. They will have 30 days to respond. Patrons who purchased tickets in person at the box office and would like a refund are asked to call (877) 733-7699 for more information."

Billy Joel told us that he keeps the main fan base happy by slaying them with hit after hit during the show, and gets to keep himself and the band sharp by digging deep into his back catalogue by playing some obscure older tunes -- which the diehards eat up: "We actually enjoy playing those tracks more than the hits. Number One, because we don't get to play them that often, and Number Two, because, y'know, they're different. So, we pulled a few chestnuts out, some things didn't work, some things did work and they kind of stayed in the set. Songs like 'Zanzibar' from 52nd Street, because we got a trumpet player now, and the guy just blows the audience away when he plays. And I took 'Root Beer Rag' out of the mothballs -- I wasn't even sure if I was going to be able to play that anymore."
