John Mayer Admits 'I Was Just a Jerk'

As well-known for putting his foot in his mouth as he is for his guitar prowess, John Mayer says he understands the public perception.

"I was just a jerk," the musician, 35, tells Anthony Mason during an interview airing this weekend on CBS Sunday Morning at 9 a.m. EST.

"It’s very liberating when you finally realize it's impossible to make everyone like you," he explains. "I wanted everybody to like me. I thought I was one shuck and jive away in every direction."

Now dating Katy Perry and dipping a toe back into live performing (he plans to tour to promote his recent album Born and Raised over the summer), Mayer gave the interview ahead of a benefit concert he held in his adopted home state of Montana last month. It was the first time he had sung live in close to two years, thanks to a persistent throat granuloma that Mayer had surgery for twice.

"It's been a crazy couple years thinking that I got it and finding out I didn't. I went to the doctor a couple weeks ago, we looked at my throat and the thing is gone," he said from the stage prior to launching into "Speak for Me."

However, he admonished the crowd to "lower your expectations. [My voice] is not going to sound like it normally sounds. I'm going to sing some songs for you for the first time in awhile. I'm going to do my best ... I'm going to try."
