Since I can never keep my mouth shut when I read Depp-related tidbits
I'm not sure, but I think that #2 (Stephen Jones and the mugging) was just a joke. They did do a recording session(s) together, though, and Johnny plays lead guitar on a song with Jones' band, Babybird that was released last year. He also directed the video
#6: The claim that Johnny owns a vineyard or makes his own wine has been refuted many times. He does love wine, though, and surely has it shipped to him.
#7: The West Memphis Three now have a new hearing scheduled, I think for around September, to look at the DNA evidence that would quite likely exonerate them. Johnny, Eddie Vedder, and Patti Smith among others performed in a concert last summer in Little Rock, AR to help raise funds and awareness for this cause.
I'm pretty sure everything else is totally true. The guy is a class act, all the way.
