In latest 'Queen: The Greatest' episode, Brian May reveals origin of Queen's 'most enigmatic song'

Ahead of the release of the box set focused on Queen's 1973 debut album, the band issued a 7-inch vinyl single of "The Night Comes Down." The latest episode of the band's Queen: The Greatest video series now focuses on the creation of that song.

According to a press release, the song, written by guitarist Brian May, is "perhaps the most enigmatic song in Queen's five-decade catalogue" due to its "otherworldly instrumental," "soul-baring lyric" and the fact that the band never performed it live.

The Queen I box set, out now, comprises 63 tracks with 43 brand-new mixes, as well as alternative takes, demos and rare live tracks.
