Drummer Nick Mason will be on hand for the launch of Pink Floyd Week on NBC's "Late Night with Jimmy Fallon." He's slated to appear on Monday's show, but not to perform.  The rocker will be sitting down for an interview segment, while The Shins are the night's musical guest.  In keeping with the week's theme, The Shins will play the "Dark Side of the Moon" track "Breathe" when they step in front of the cameras.  Pink Floyd's Roger Waters will follow as an "interview guest" on Tuesday.  But he is also expected to perform.  He'll be joining Foo Fighters on a rendition of "In The Flesh," from "The Wall."  MGMT will keep Pink Floyd Week going on Wednesday by playing "Lucifer Sam," from 1967's "The Piper at the Gates of Dawn."  Country star Dierks Bentley is on board for Thursday to perform

"Wish You Were Here," and Pearl Jam will wrap up Pink Floyd Week with the song "Mother," which is also from "The Wall."
