By the late '70s, George Harrison felt alienated from the popular music scene, and his relationship with his record label was done no favors when it rejected this album's original version. After John Lennon's murder, Harrison retooled "All Those Years Ago" as a tribute to his fallen bandmate. Ringo Starr had already played drums on the track, and Harrison invited Paul and Linda McCartney to add backing vocals to make it a true reunion of the surviving members. The song was a sizable hit, and, along with tracks such as "Teardrops" and "That Which I Lost," represents Harrison at his most melodic and heartfelt. Two covers of Hoagy Carmichael tunes—"Baltimore Oriole" and "Hong Kong Blues"—reflect where Harrison's musical interests were taking him, while "Blood from a Clone" cynically apes the sounds then heard on the radio while indicting the music industry for being fickle and shallow. Always one to speak his mind, Harrison in his own way was as much a confessional writer as John Lennon, with eclectic musical interests that kept him forever evolving even as he grew more disenchanted with pop music itself.
