Midway through Fleetwood Mac’s Pinnacle Bank Arena concert Saturday night, in Lincoln, Nebraska, drummer Mick Fleetwood suddenly became ill.

“Mick is really sick,” Stevie Nicks told the crowd, adding that Fleetwood was backstage throwing up. “We feel terrible, but we can’t really make him play. Give us a minute, and we’ll figure out what to do.”

That turned out to be playing two more songs.

A drum tech named Steve took over Fleetwood’s kit for “Go Your Own Way,” which is usually the song the band plays before two encores.

Then, after a short break, Christine McVie returned to the stage at a grand piano, playing and singing “Songbird” accompanied by guitarist Lindsey Buckingham.

“Poor old Mick is really sick,” McVie said. “I sing this for him and for all of you.”

“Songbird” has been the final song on the band’s “On With the Show” tour, usually capping a 2½ hour show. Saturday’s truncated set ran just over 90 minutes.
