In the US the song was included on the album On the Third Day, while in the UK the song was omitted from that album but featured a year later on the band's first compilation album, also entitled Showdown. In 2006 the remastered issue of On the Third Day would feature the song on the album on both sides of the Atlantic for the first time. The song showed a change of style for ELO, with a funkier backbeat beneath the band's trademark sweeping strings, and the inclusion of a clavinet. The record was a favourite of John Lennon at the time, who dubbed the band "Son of Beatles" in a US radio interview. Marc Bolan of T. Rex was at the session where the song was recorded and played on several of the band's tracks at that time, but did not play on Showdown itself. Instead, Jeff Lynne borrowed Bolan's Gibson Firebird guitar to play over the instrumental break.
B-side
The B-side, "In Old England Town", is an edited instrumental version of "In Old England Town " by Lynne. Recorded in 1972, this was the opening track of the band's second LP ELO 2, and was one of two songs on the album that featured Roy Wood on cello and bass guitar, the other being "From the Sun to the World". Shortly after recording these tracks, Wood abandoned ELO to form Wizzard, and he was not originally credited on the LP sleeve. Normally Wood and Lynne co-produced all their collaborations, but it is unknown whether Wood was involved in the production of either track.
A planned concept album entitled "The Lost Planet" was quietly abandoned and sessions for the second LP proper began May 1972. Two new Jeff Lynne songs, "From the Sun to the World" and "In Old England Town" were the first to be recorded and included Roy Wood on bass guitar and cello, but in little more than a month, the co-founder of the ELO concept left the group. —Rob Caiger, 28 March 2006, ELO II Remaster
The song was included in ELO's first 1972 tour playlist, simply titled Jeff's Boogie #2, and had a different set of lyrics. This early live version was filmed for Granada Television's Set of Six in 1972; that is the only live footage of the original ELO known to exist. These songs were released on a 2006 DVD called ELO – Total Rock Review. The Moog intro of the edited version was later sampled and included on Paul Weller's hit single "The Changingman", as was the main riff from "10538 Overture".
Lynne re-recorded the song in his own home studio. It was released on the compilation album along with other re-recorded ELO songs, under the ELO name.
