The Beatles loved him, and pop devotees the world over will never forget him. Harry Nilsson was a force of nature, a creature of excess whose voice could convey unbearable tenderness, and an artist whose muse was so unpredictable that he followed his biggest pop hits with an album of pre-rock standards. Nilsson had a startling range—even after he shredded his vocal cords in a session with John Lennon—and though a world-class songwriter, had his biggest hit with Badfinger's “Without You”. His juggling of romance, eccentric humour and underlying turmoil created a one-of-a-kind catalogue.
