"You're My Best Friend" is a song by the British rock band Queen, written by the band's bass player, John Deacon, who wrote it for and about his wife. It was first included on the 1975 album A Night at the Opera, and later released as a single. The ballad also appeared on the Live Killers (1979) live album, and on the compilation albums Greatest Hits (1981), Absolute Greatest (2009) and Queen Forever (2014). The song reached number seven in the UK Singles Chart and number 16 on the US Billboard Hot 100. It is certified platinum by the RIAA in the US with over one million copies sold. The song has since featured in television, film, and other media, such as The Simpsons and Family Guy. History Deacon wrote the song for his wife, Veronica Tetzlaff. In this song, he plays a Wurlitzer electric piano in addition to his bass guitar work. The characteristic "bark" of the Wurlitzer's bass notes plays a prominent role in the song. During live performances, a Grand Piano was used rather than an electric, and it would be played by Freddie Mercury, while Deacon played the bass guitar just like in the original recording. The song would be performed live by the band from the Summer Gigs 1976 Tour up to the end of the North American leg of The Game Tour in 1980. It was then dropped from the rest of the tour, and would not be played live again until after the death of Mercury. The song was used in several TV shows and films such as Hot in Cleveland, Will & Grace, EastEnders, My Name is Earl, The King of Queens, Good Omens, The Break-Up, the end credits of I Now Pronounce You Chuck and Larry, The Simpsons, Shaun of the Dead, Peter's Friends, The Secret Life of Pets, and the Family Guy episode "Farmer Guy". Music video The music video, directed by Bruce Gowers, shows the band in a huge ballroom surrounded by over one thousand candles, including a huge chandelier hung from the ceiling. The video was filmed in April 1976 at Elstree Studios, near London. Additionally, Deacon is seen playing a grand piano rather than the Wurlitzer he used on the recording. Composition The song was composed by John Deacon in the key of C major with a meter of 4/4, in swing feel. The album A Night
