Easily one of Harry Nilsson's most underrated songs, "Don't Forget Me" was also the lost gem of the ill-fated Nilsson/John Lennon collaboration, Pussy Cats. The over-indulgence and lack of focus that permeated that album took a vacation for three and a half minutes, and you have a true masterpiece. An exquisitely written, graceful pop ballad -- bordering on being a standard -- its lyrics are essentially a love letter from a recently divorced man to his ex-spouse. Despite its sad, downcast tone, lines like "You know I'll miss you/and miss the alimony too" can't help but make you giggle. An obscure (but talented) singer, John Cowan covered the song nicely on the Everybody Sings Nilsson tribute album.
