John Mayer performed at his first concert in nearly two years, a fundraiser he helped organize to benefit firefighters that helped save his home and others from a Montana wildfire.

The Bozeman Daily Chronicle reported ( http://bit.ly/SajIra) that Mayer started with his first live performance of "If I Ever Get Around to Living," at a concert in Bozeman on Wednesday that included Zac Brown and raised more than $100,000.

The 8,500-acre fire raged in late August near Livingston, while Mayer was in Los Angeles receiving treatment for a growth near his vocal cords.

In May, a second granuloma was removed. The singer-songwriter says Botox injections used to keep his vocal cords from pressing together while they heal have limited his ability to hit high notes.
