This is an incomplete list of original songs composed by the rock band Phish. Certain "sections" of songs have been played separately from time to time, but are not listed below. For instance, the middle section of "Guelah Papyrus" was sometimes played by itself under the name "The Asse Festival.” Before "The Moma Dance" had lyrics, it was called "Black-Eyed Katy.” “Shafty" was once called "Olivia's Pool,” and featured a different arrangement. "Taste" was once known as "The Fog That Surrounds" and contained a slightly different arrangement. And many sections of the multi-part epic "Fluffhead" have been played outside of the song. Some of these sections include "Clod", "The Chase", "Who Do? We Do!!" and "Bundle of Joy.” Phish also performed several songs by The Dude of Life, a friend and collaborator of the band, but those are not listed here, with the exception of songs that The Dude of Life purposely gave to Phish for use in their catalog. Also, songs from the band's solo careers that were also performed by Phish are listed here.
