The lyrics of the song are composed of two of Robert Calvert's science fiction poems, the first verse being "The Starfarer's Despatch", which he had recited at shows whilst being the "resident poet" in the band in 1971, and the second being "The Clone's Poem". Both of these poems were published amongst a collection of his poetry issued as Centigrade 232, published by Quasar in 1978. Throughout the song is a rhythmic electronic pulse. This repeated sound is the Morse Code for SOS (dot-dot-dot, dash-dash-dash, dot-dot-dot).[citation needed]
The song was a popular addition to the band's live set and even remained after Calvert's departure from the band in 1979. A more aggressive version of the song with vocals by Brock was issued on the Live Seventy Nine album in 1980.[citation needed]
On 14 November 2019, the group recorded a session for Marc Riley's BBC Radio6 Music show, playing "65 Million Years Ago", "Last Man on Earth", "Spirit of the Age" and "Silver Machine".[1]

2004 single
In 2004 the band recorded a new studio version of the song which was issued as a single in two different formats. The first verse featured a vocal by tabloid journalist Matthew Wright who, while interviewing the band on a London radio show, had revealed that he was a big fan of the band. This version was included on their Take Me to Your Leader album.
