Watch, Roger Waters Cover of John Lennon’s Classic Song “IMAGINE”

Bruce Springsteen and Roger Waters joined an all-star lineup of comedians final night time as they acknowledged wounded army personnel at the Bob Woodruff Foundation’s annual Stand Up for Heroes profit.

Roger Waters led a group of wounded veterans through an emotion-packed run of songs that included Floyd‘s ‘Comfortably Numb’ and ‘Wish You Were Here,’ John Lennon‘s ‘Imagine,’ Leonard Cohen’s ‘Hallelujah’ and Sam Cooke’s ‘A Change Is Gonna Come.’
