"Lou Reed wrote this on a Sunday Morning around 6am. Andy Warhol, who helped finance the album, suggested he write a song about the paranoia associated with the effects of a drug wearing off. Reed wrote this for Nico but then decided not to let the German ex-model sing it. Instead he impersonated her himself. In The Velvet Underground: An Illustrated History of a Walk on the Wild Side, it is reported that Nico thought of this uncharacteristically upbeat tune as "Sun Day Mourning." It tells you a bit about how Nico's mind worked, and also the split that The Velvet Underground would have with Nico and her mentor Andy Warhol. This song is all about last-minute changes. The inclusion of the track on their first album was literally penciled in, Reed decided to take over vocals at the last minute as they walked into the studio to record it, and John Cale noticed a celesta in the studio and decided to include the instrument for the song on the spot. Cale also played the viola on the song."{taken from http://www.songfacts.com/detail.php?id=6079]
