Def Leppard have added a little something to their upcoming 11-night Viva Hysteria residency at The Joint in Las Vegas -- their own Rock and Roll Fantasy Camp. In conjunction with the official Rock and Roll Fantasy Camp, this one will be held April 4th to the 7th, and will work as instructors and mentors to the campers.

It won't be the first camp for guitarists Phil Collen and Vivian Campbell, who've participated before. And this is only the second camp dedicated to a sole artist -- Cheap Trick being the first a few years ago.

Def Leppard start their Vegas residency on March 22nd and wrap up on April 13th. They also just announced a one-off as headliners of Hell Fest in Clisson, France on June 21st.

There is a Rock and Roll Fantasy Camp taking place this weekend in Vegas, and among those on hand are Alice Cooper and Ace Frehley.
