John Mayer is recovering from throat surgery. The outspoken singer who never has a problem speaking on his past relationships and the type of women he does not prefer will have to shut his mouth for a while.  Mayer, underwent surgery this past Thursday to remove a granuloma that had caused inflammation on his vocal chords. John says

 "I am now on complete vocal rest for a month or more"

His vocal problems lead him to cancel numerous concerts and it also delayed him from working on his upcoming album.
