John Mayer sat in with The Roots band on Late Night With Jimmy Fallon and also did an interview.
Mayer talked at length about his throat issues that are keeping him from singing. Although, he did sing a chapter of the "50 Shades Of Grey" book from his Kindle.
Fallon also brings up where when Mayer first came out as "Little Johnny Mayer" and talking about working with Eddie Vedder.
Mayer also says he will continue to wear his hat no matter what anyone says. Guess since he can't sing, he is answering a lot of questions about the hat.
What do U think of the hat?-DocFB
