Singer Gavin Degraw has axed a performance at a music festival in Washington, D.C. on Saturday (24Mar12) after falling ill.
The Chariot star, who is currently competing on U.S. reality show Dancing with the Stars, has been ordered to rest his vocals and as a result, he's had to pull out of the gig at the ShamrockFest this weekend.
Taking to on Friday (23Mar12), he wrote, "Bummed I can't perform at shamrock fest tmrw (tomorrow). was looking forward to it, but, dr (doctor's) orders I am now on vocal rest."
