John Mayer can`t sing for six months

London: John Mayer has been advised not to sing again for six months after undergoing throat surgery.

The 34-year-old underwent an operation to remove a granuloma from his vocal cords last Monday and is now recovering at home, reports contactmusic.com. "Well, here I am. Silent for the next few months, no singing for probably six, but all signs point to this being the last step in getting to perform again. Back to notebooks and iPad to communicate for the time being," Mayer posted on his Tumblr.com blog. IANS
