"Forever Autumn" is a song written by Jeff Wayne, Gary Osborne and Paul Vigrass. The original melody was written by Wayne in 1969 as a jingle for a Lego commercial. Vigrass and Osborne, the performers of the original jingle, added lyrics to the song and recorded it for inclusion on their 1972 album Queues. Their interpretation was also released as a single and gained moderate commercial success in Japan, selling more than 100,000 copies and becoming a top-20 hit on the country's record chart.
Vigrass and Osborne performed it on their 1972 album, Queues. This version also appeared as a single.
Hayward performed it on the 1978 album Jeff Wayne's Musical Version of The War of the Worlds. A slightly different mix (notably excluding the narration from the album) was released as a single. The latter version was included in the Moody Blues' box set Time Traveller. Although sometimes falsely credited as being an original single by the Moody Blues itself, Hayward has performed the song live with that group.
