"Put Out the Fire", the album's most traditional Queen song, later appeared on the Queen Rocks compilation in 1997. A new video was also produced for the accompanying video compilation, featuring a live performance of the song intercut with footage of fire and explosions. "Life Is Real (Song for Lennon)" Mercury wrote "Life Is Real" as a tribute to John Lennon, whose murder in 1980 had also previously prompted the band to perform his song "Imagine" on tour. It is also one of the few Mercury songs whose lyrics were written before the music. "Life Is Real (Song for Lennon)" was not played live on the European leg of the tour. It was only played a couple of times on the North American leg. "Calling All Girls" The first Queen song written by Taylor to be released as a single (albeit in selected countries, including the US and Australia, but not the UK), "Calling All Girls" failed to create much of an impact on the charts where it peaked at number 60 in the US and number 33 in Canada, despite its music video based on the George Lucas film THX 1138. Taylor composed "Calling All Girls" on guitar and played the feedback noises during the song's break. Queen never performed the song in Europe, and a live recording from Japan in 1982 is commercially available on the Queen on Fire – Live at the Bowl DVD, where "Calling All Girls" accompanies the photo gallery. The single was released in July 1982. "Las Palabras de Amor (The Words of Love)" May's lyrics for "Las Palabras de Amor" were inspired by Queen's close relationship with their Latin-American fans, and have been interpreted as an allegory for the Falklands War. A top 20 hit in the UK, "Las Palabras de Amor" marked the band's sixth single to feature at least one in-studio appearance on Top of the Pops, the others being "Seven Seas of Rhye" (three performances, only partially still existing), "Killer Queen" (two performances, one of which only partially exists), "Now I'm Here" (two performances, with only one of them partially existing) and "Good Old-Fashioned Lover Boy" (one performance). For this mimed performance, May is seen playing a grand piano, although he only played synthesisers on the recording. May also sang lead vocals for the harmonised line "this night and evermore".
