Nilsson, Harry. Brooklyn-born, powerfully piped singer-songwriter equally famous for well-realized retro-pop albums such as Nilsson Schmilsson (1971) and for being John Lennon’s drinking buddy/partner in crime during the latter’s “Lost Weekend” period in Los Angeles. Though his adept melding of Tin Pan Alley and Sergeant Pepper idioms suggested an artist of limitless possibility in the late ’60s and early ’70s, his increasingly sozzled state put him into a mid-’70s artistic decline from which he never recovered. (His tipple of choice was the Brandy Alexander, which the admiring Lennon referred to as a “milkshake”). Since his 1994 death, however, Nilsson’s oeuvre has acquired significant hipster cachet, with his oeuvre lavishly repackaged by BMG and his song “One,” as sung by Aimee Mann, used prominently over the credits of P.T. Anderson’s 1999 epic Magnolia.
