Coronavirus continues to wreak havoc on live music, and its latest victim is Elton John's Farewell Yellow Brick Road Tour. He has just postponed his dates from March 26 through May 2 (including his NYC-area shows at Madison Square Garden, Barclays Center, Prudential Center, and Nassau Coliseum), though his shows from May 22 onwards are still on. Via press release:

After serious consideration, it is with deep regret that Elton John will postpone a portion of upcoming North American dates on his Farewell Yellow Brick Road tour from March 26 through May 2, 2020. The May 22 thru July 8 performances remain as scheduled. This tough decision has been made with the safety and well-being of his fans put to the fore, at a time when health services are under increased pressure and with the concern that these gatherings risk accelerating the spread of the Coronavirus [COVID-19].
The ELTON JOHN FAREWELL YELLOW BRICK ROAD TOUR dates being rescheduled are as follows:

March 26 Indianapolis, IN Bankers Life Fieldhouse
March 28-29 Toronto, ON Scotiabank Arena
April 2-3 Montreal, QC Bell Centre
April 6-7 New York City, NY Madison Square Garden
April 10-11 Brooklyn, NY Barclays Center
