Jazz is the seventh studio album by the British rock band Queen. It was released on 10 November 1978 by EMI Records in the United Kingdom and by Elektra Records in the United States. Produced by Roy Thomas Baker, the album artwork was suggested by Roger Taylor, who previously saw a similar design painted on the Berlin Wall. The album's varying musical styles were alternately praised and criticised. It reached #2 in the UK Albums Chart and #6 on the US Billboard 200. Jazz has sold over 5 million copies worldwide.

"Mustapha" is a song written by Freddie Mercury. It was released as a single in 1979.

The lyrics consist of English, Arabic, Persian and possibly a number of invented words. Some understandable words are "Mustapha", "Ibrahim" and the phrases "Allah, Allah, Allah we'll pray for you", "salaam alaykum" and "alaykum salaam".

In live performances, such as the performance on Live Killers, Mercury would often sing the opening vocals of "Mustapha" in place of the complex introduction to "Bohemian Rhapsody", going from "Allah, we'll pray for you" to "Mama, just killed a man...". However, sometimes the band performed an almost full version of the song, with Mercury at the piano.

"Fat Bottomed Girls" was written by Brian May with lead vocals shared by Mercury and May, who sings lead on the chorus. On stage Mercury sang the entire song, with Roger Taylor and May doing harmonies. Both guitar and bass are played in drop-D tuning for this song, a rarity for Queen.

"Jealousy" was penned by Mercury and features May playing his Hairfred acoustic guitar. The guitar had been given a replacement hardwood bridge, chiselled flat, with a small piece of fret wire placed between it and the strings, which lay gently above. The strings produce the "buzzing" effect of a sitar. This effect had already been used on "White Queen (As It Began)", from Queen II. All vocals were recorded by Mercury.
