The Puppy Song: "The Puppy Song" is a Harry Nilsson song that appeared on his album "Harry" released in August 1969.  Nilsson originally wrote this song at Paul McCartney's request for Mary Hopkin, an 18-year-old singer that McCartney had signed to Apple Records and whose first album, "Post Card" would feature her version of Nilsson's song.

Son of Schmilsson: Son of Schmilsson is the eighth album by American singer Harry Nilsson.  Nilsson was being pressured to produce a follow-up album similar to his 1971 breakthrough, "Nilsson Schmilsson", but instead, he created a more eccentric work.  The album was produced by Richard Perry and features musical contributions from former Beatles Ringo Starr and George Harrison.

Knnillssonn: Knnillssonn is the fourteenth album by Harry Nilsson.

RCA agreed and had prepared to promote the album heavily as a comeback album after his previous efforts were mostly missed by the public.  Shortly after the album was released, Elvis Presley died.  Nilsson and Presley shared the same record label, RCA.  The sudden death of Elvis resulted in a complete overhaul for RCA's promotion plans and money budgeted for promoting Knnillssonn was redirected to Presley.
