May wanted to emulate Rick Nelson's and Presley's longtime guitarist James Burton, and at Macks's suggestion used a Fender Esquire rather than his regular Red Special for the recording session. Billboard Magazine described Brian May's guitar playing as being 'stunning in its simplicity.' Cash Box called it a 'hip shakin' rockabilly romp' and an 'upbeat tune.' Having written 'Crazy Little Thing Called Love' on guitar and played an acoustic rhythm guitar on the record, for the first time ever Mercury played guitar in concerts, for example at Live Aid at Wembley Stadium, London in 1985. The entire song was reportedly recorded in less than half an hour (although Mack says it was six hours). The three of them, with their then new producer Reinhold Mack, recorded it at Musicland Studios in Munich.

Mercury took it to the studio shortly after writing it and presented it to Taylor and John Deacon. Roger Taylor added in an interview that Mercury wrote it in just 10 minutes while lounging in a bath in the Bayerischer Hof Hotel in Munich during one of their extensive Munich recording sessions. The song was written by Mercury as a tribute to his musical heroes Elvis Presley and Sir Cliff Richard. The style of the song was described by author Karl Coryat as rockabilly in his 1999 book titled The Bass Player Book. The song was played live on 20 April 1992 during The Freddie Mercury Tribute Concert, performed by Robert Plant with Queen.

Since its release, the song has been covered by a number of artists.

Queen played the song live between 19, and a live performance of the song is recorded in the albums Queen Rock Montreal, Queen on Fire – Live at the Bowl, Live at Wembley '86 and Hungarian Rhapsody: Queen Live in Budapest. Having composed 'Crazy Little Thing Called Love' on guitar, Mercury played rhythm guitar while performing the song live, which was the first time he played guitar in concert with Queen. It was the band's final single release of the 1970s. It topped the Australian ARIA Charts for seven weeks. The song peaked at number two in the UK Singles Chart in 1979, becoming the group's first number-one single on the Billboard Hot 100 in the US in 1980, remaining there for four consecutive weeks. Written by Freddie Mercury in 1979, the track is included on their 1980 album The Game, and also appears on the band's compilation album Greatest Hits in 1981.
