Pink Floyd - Lucifer Sam SYD BARRETT

the lyric frequently refers to Lucifer Sam as a cat, some speculation has arisen as to whether this was in fact slang (“a hip cat“) for a man, real or imagined, in some type of relationship with Barrett's then-girlfriend, Jenny Spires (referred to in the song as “Jennifer Gentle“).[3] However, Sam was simply Barrett's Siamese cat (and is referred to as such in the first line: “Lucifer Sam, Siam cat“); the track was originally called “Percy the Rat Catcher“ during the recording sessions, which took place between April and June 1967.[4]
