Earth, Wind & Fire postpones concert with Lionel Richie because of 'medical emergency'

For San Francisco fans of Lionel Richie and Earth, Wind & Fire, the party at Chase Center ended before it even started.

Earth, Wind & Fire abruptly called off its concert at the city's venue on Thursday, notifying fans in a social media statement that the cancellation was "due to a medical emergency involving a member of our band." A spokesperson for the San Francisco Fire Department confirmed to the Los Angeles Times that personnel were dispatched at 5:30 p.m. to respond to a medical emergency at Chase Center. One person was transported to a hospital via private ambulance, but the individual's identity was not disclosed. TMZ reported that the Fire Department responded to a "cardiac incident."

A representative for Earth, Wind & Fire did not provide additional details. The band said in its post that it has rescheduled Thursday's show for a later date to be announced soon and that tickets will be valid for the new date. "We sincerely apologize for the unexpected change and appreciate everyone's understanding," the band said.

Live Nation announced Richie and Earth, Wind & Fire's joint Sing a Song All Night Long tour in January. The tour kicked off in June but quickly hit a snag when Richie also suffered an unspecified health issue while on the road. Richie, 77, postponed a stop at Chicago's United Center and another show at the Schottenstein Center in Columbus, Ohio, after he brought his first tour stop to an abrupt end.

The Grammy-winning hitmaker of "Hello" and "Say You, Say Me" unexpectedly stopped the concert at the Grand Casino Arena in St. Paul, Minnesota, after taking a seat onstage multiple times during his performance of "Dancing on the Ceiling" and telling his audience he felt "dizzy," according to videos shared on social media.
