Demo Song
Background Information
In Bill Flanagan’s book, U2 At the End of the World, he spends time with U2 in the studio while they are recording the Zooropa album and at one point he gives a list of songs that are being worked on for the album. Many are familiar as songs that make it onto the album, but some are not, or would only show up later in life. “Sponge” is one of these songs. Each song listed is under one of three categories, and “Sponge” falls under “Vibes” as opposed to “Songs” or “Soundtracks”.
