My wife made a kick-ass compilation CD for her sister on Mother's Day with all songs having the mom/mama/mother theme. The song she chose to lead off the album is just outstanding. It's Roger Waters live in 2007 singing Mother, with incredible female backing vocals. It sends chills up my spine several times throughout the song. When Roger starts singing, when the diva at 2:22 starts singing "hush now baby, baby don't you cry", and at 5:00 when she sings "Mama's going to keep baby healthy and clean."
And, how GREAT does Roger sound and look?
