Billy Joel announced on Tuesday that he is rescheduling several dates along his current tour so that he can focus on recovering from a recent surgery.

Billy Joel postpones his tour to take a four-month break to focus on his health and recovery from an undisclosed 'medical condition.' He says, 'My health must come first.'

As he sang his 1980 track “It’s Still Rock and Roll to Me,” Joel attempted his classic microphone trick for the audience. Concertgoers said he was twirling the mic and lost his balance as he threw it toward the crowd. He subsequently fell on his back and his band rushed to his aid to help him back up.

Billy Joel announced on his Facebook page Tuesday that he had to reschedule eight concerts due to a medical condition, with Joel needing time to "recover from recent surgery and to undergo physical therapy under the supervision of his doctors.
