The Beatles must be proud.
In "Hey St. Jude," a new video for St. Jude Children's Hospital, Jennifer Aniston, Jon Hamm, Keith Urban, Michael Strahan, Lady Antebellum and a slew of celebrities team up with the patients, nurses, doctors and staff to sing their version of the Paul McCartney's 1968 Beatles' classic, "Hey Jude."
Also lending their vocal talent to the clip? Jordin Sparks, Kellie Pickler, Darius Rucker, Randy Owen, Betty White, Jimmy Kimmel, Ellen DeGeneres and Shaun White.
