Prelude are an English based vocal harmony group, who in their most famous line-up consisted of Brian Hume (vocals, guitar), his wife Irene Hume (vocals) and Ian Vardy (guitars, vocals). They formed in their native Gateshead in 1970.
Prelude began to write their own material and built a following on the folk circuit and in 1973 they recorded their first album, How Long Is Forever?, on Dawn Records at Rockfield recording studios in Wales. From it came their best known recording, an a cappella version of the Neil Young song "After the Gold Rush", on Dawn. In the UK, it entered the Top 50 on 26 January 1974, had a nine-week stay, peaking at Number 21. In America, it entered the Billboard Hot 100 on 5 October 1974, and had a 13-week stay, peaking at #22.
