"Triad" is a song written by American singer-songwriter David Crosby in 1967 about a ménage à trois. It was recorded by the Byrds that year, while Crosby was a member of the band, but their version went unreleased at the time and was not issued until twenty years later. Jefferson Airplane released a version of the song in 1968 on their Crown of Creation album and a live version performed by Crosby was included on Crosby, Stills, Nash & Young's 4 Way Street in 1971. Composition and recording "Triad" was written while Crosby was a member of the rock band the Byrds, who were at that time recording their fifth studio album, The Notorious Byrd Brothers. The song's lyrics concern a ménage à trois and were largely inspired by the sexual freedom that Crosby enjoyed at his home in Beverly Glen in Los Angeles. Byrds biographer Johnny Rogan has described the song's subject matter as being perfectly in keeping with the "free love" hippie philosophies of the day. The song also alludes to author Robert A. Heinlein's science fiction novel Stranger in a Strange Land, with references to "sister lovers" and "water brothers". Although the Byrds did record "Triad" and performed it live during a September 1967 engagement at the Whisky a Go Go, it was not included on The Notorious Byrd Brothers album. According to Crosby, bandmates Roger McGuinn and Chris Hillman felt that its subject matter was too controversial, with McGuinn allegedly deriding the song as a "freak-out orgy tune". However, this has since been denied by Hillman, who has stated, "I don't think it was a moral decision. The song just didn't work that well. David was drifting and bored and wanted to do something else, and that song just added fuel to the fire." There had been growing animosity between Crosby and the rest of the band throughout 1967, which, coupled with the discord over "Triad", contributed to McGuinn and Hillman's decision to fire him from the band in October of that year. Releases Following his departure from the Byrds, Crosby gave the song to the band Jefferson Airplane, who included a recording of it on their 1968 album, Crown of Creation. This version also appears on Jefferson Airplane singer Grace Slick's compilation album The Best of Grace Slick. A live recording of "Triad" performed by Crosby himself was later included on Crosby, Stills, Nash &
