John Mayer is finally ready to sing again. The boyfriend of Katy Perry performed live for the first time since he was diagnosed with the throat condition granuloma in September 2011 and told by doctors he needed to allow his vocal chords some time to heal.

It ended up taking almost a year and a half, but Mayer is finally back in singing shape. He performed at the Concert to Benefit the Fighters of the Pine Creek Fire in Montana, and admitted to the crowd that he still isn’t at 100 percent.

“It’s been a crazy couple of years with thinking that I got it, finding that I didn’t, thinking that I got it, finding that I didn’t, going on voice rest, going a little mad,” he tells his audience in the above video. “I went to the doctor a couple weeks ago and we looked at my throat and the thing is gone.”

He adds, “Lower your expectations. … It’s not going to sound like it normally sounds, but I’m going to sing some songs for you guys.”

Mayer ended up performing “Speak for Me,” “Whiskey, Whiskey, Whiskey” and “If I Ever Get Around To Living.” It seems like he considered the concert a win, because it has been announced that Mayer will perform alongside Fleetwood Mac, Maroon 5, the Black Keys, Dave Matthews Band, Frank Ocean, Billy Joel, Willie Nelson, Hall & Oates and B.B. King at the 2013 New Orleans Jazz & Heritage Festival on April 26.
