UPDATE [4/8/19]: Fleetwood Mac has postponed their upcoming U.S. tour and canceled their recently announced slot at New Orleans Jazz & Heritage Festival as Stevie Nicks recovers from the flu. A new replacement for their May 2nd slot has yet to be announced. Head here for details.

On Thursday, Fleetwood Mac was added to the May 2nd lineup for the 50th-anniversary edition of the New Orleans Jazz & Heritage Festival. Fleetwood Mac is currently at the tail end of a lengthy North American tour, with a number of dates in Europe and Australia set to take place later this year.

The band’s addition to the lineup came as a replacement for The Rolling Stones, whose headlining set was canceled along with the postponement of the band’s entire U.S. tour due to a health issue affecting Mick Jagger. On Thursday, Jagger underwent heart valve surgery and is expected to make a full recovery. Reports have indicated that The Rolling Stones’ postponed U.S. tour could be rescheduled to begin as early as July.

However, a pair of recent show postponements has Jazz Fest patrons somewhat on edge. Amid the announcement that they will fill in for The Rolling Stones at Jazz Fest, Fleetwood Mac postponed two shows this past week—April 5th at Philadelphia, PA’s Wells Fargo Center and April 2nd at Boston’s TD Garden—due to band member illness. The band has not offered any details regarding which member is ill or the extent of said illness.

Ticketholders for Fleetwood Mac’s two postponed shows can retain their original tickets for use at the forthcoming rescheduled Boston and Philly dates, the exact dates of which will be scheduled once the NBA Playoffs schedule is set.

For the sake of the band, their fans, and the organizers and patrons of New Orleans Jazz & Heritage Festival, we hope whoever in the Fleetwood Mac camp is sick makes a full recovery soon.
