Fleetwood Mac had to cut a Nebraska concert about an hour short Saturday night after drummer Mick Fleetwood became ill.

Stevie Nicks told the crowd of roughly 14,000 at Lincoln’s Pinnacle Bank Arena that “Mick is really sick” was throwing up backstage before the end of the 90-minute show.

A drum technician played “Go Your Own Way” for Fleetwood. Then Christine McVie played piano and sang “Songbird” with guitarist Lindsey Buckingham before the band ended the show.

Fleetwood Mac said Sunday in a statement online that it plans to perform its next scheduled show in Grand Rapids, Michigan, on Tuesday: “Last night’s Fleetwood Mac show in Lincoln, Nebraska ended a few songs early when the band’s founder and drummer Mick Fleetwood became ill with the stomach flu. At this time, the band is still scheduled to perform in Grand Rapids, MI on Tuesday.”
