The Lumineers have pulled out of their scheduled appearance at the Firefly Festival in Delaware on Sunday, citing an illness.
The band issued a statement saying "We were all extremely excited to be a part of this great event and share our music with you, but the health and well-being of the band along with giving the fans the best possible performance remain our top priority. Unfortunately given the circumstances, both of those things would be in jeopardy if we went ahead with our set this Sunday. We hope everyone enjoys the festival and we will be back to see you all as soon as humanly possible."
Ben Harper and Charlie Musselwhite, who are touring together, have agreed to fill in for the Lumineers.
