Let It Be (Beatles album)
George Harrison helped the  of the band, when he brought a guest musician, Billy Preston, to the sessions. All of the Beatles liked Preston, and got along while he was there. He played keyboards along with the band, and gave the records a fuller sound. McCartney's girlfriend Linda brought her daughter Heather to the studio, and they helped cheer things up. Linda sang background vocals on "Let It Be", a gospel-like song by McCartney.
