Dead & Company will not perform as planned tonight, July 6th, at Saratoga Performing Arts Center (SPAC) in Saratoga Springs, NY. The Grateful Dead offshoot announced just after 3 p.m. ET that the show was canceled “due to unforeseen circumstances.” Later in the afternoon, John Mayer posted that his father suffered a “medical emergency” and that is why he cannot play tonight’s show in Saratoga Springs. The vocalist/guitarist noted that “he is now fairly stable and will continue to undergo some procedures.”

According to the group’s brief statement, the rest of the dates on Dead & Company’s summer tour are unaffected. The tour is set to resume on Friday with a show at Jiffy Lube Live in Bristow, VA before moving on to Citizens Bank Park in Philadelphia, PA (7/10) and The Pavilion at Star Lake in Burgettstown, PA (7/12) before finally wrapping with two nights at Citi Field in New York, NY (7/15, 7/16).
