On Friday, JOHN MAYER announced that he's pulling out of two shows . . . one with TONY BENNETT in L.A. and the iHeartRadio Music Festival in Las Vegas . . . AND he's delaying his album.
--The reason is a granuloma . . . which is an inflamed mass of tissue in his throat, near his vocal chords. He has to recover before he can go back to singing.
--He says his album, "Born and Raised", still needs more vocals so it's going to be pushed to sometime next year instead of coming out in the next few months.
--Mayer says, quote, "I'm not sure how long or short a period of time it will be. I've got the best doctors in the country looking after me and I will be singing and touring again as soon as I get the 'all clear.'"
