Lennon & Nilsson 1974, March of Dime Benefit, Central Park, NY
Of the OFFICIAL ones, here are some Beatle related thoughts.
Pandemonium Shadow Show (1967 RCA debut).
Derek Taylor bought a box of them and gave them to the Beatles because of Harry's "You Can't Do That." Lennon reportedly took acid to the LP for days. After that, John & Paul mentioned Nilsson as their favorite singer AND favorite band at the Apple Press Conference.
Son of Schmilsson (1972) features Ringo and George Harrison.
Son of Dracula (1974) is the soundtrack to the movie starring Ringo and Harry
Pussy Cats (1975) was produced by John Lennon
Not his best album as Nilsson's voice ruptured because of all the cocaine and partying the two were doing.
Every Man Has A Woman (1984)
A Yoko Ono covers album. Harry contributed 3 tracks
Harry Does Yoko
Harry's demos for Every Man Has a Woman (with 4 or 5 songs that didn't make the album). These are demos and are really for fans only.
There are a bunch of little connections (like Ringo's "Harry's Song" from last year) or Ringo's Handgun promos for Harry (Stop & Smell The Roses bonus track) and the Lennon demo of "Only You" (with Harry in the background) from Lennon's Anthology Box. They were all really close in the 70s and so there are dozens and dozens of musical connections.
