"Welcome To The ‚Garden Party‘" is a 1986 single by British neo-progressive rock band Marillion released exclusively in West Germany to accompany a series of concerts the band played at festivals in that country as second bill to Queen, following their commercial breakthrough with the album Misplaced Childhood and the hit singles "Kayleigh" and "Lavender" the year before. The single was released on 7" and 12" vinyl; neither version contained any new or previously unreleased material. The 7" and 12" versions contained completely different recordings from each other. The A-side, "Garden Party", originally the second single from the band's debut album, Script for a Jester's Tear, had reached #16 on the UK Singles Chart in 1983, but—like all Marillion singles before "Kayleigh"—had failed to chart in Germany. However, the single received little airplay and failed to enter the German top 100.

While the 7" single contained the edited studio version of "Garden Party" also found on the original 1983 7" single (on which the line I'm fucking was replaced with I'm miming to avoid airplay problems), the A-side of the 12" single featured a live recording made at De Montfort Hall, Leicester, on 5 March 1984, previously released on the 1984 live album Real to Reel (on which the aforementioned line is sung by the audience). The B-side of the 7" single was the edited version of the 1984 re-recording of "Market Square Heroes" (originally the band's 1982 non-album debut single) first released on B-side of the 1984 7" single Punch & Judy. In its place, the B-side of the 12" single featured the two live tracks "Kayleigh" and "Script for a Jester's Tear". These versions, recorded at London's Hammersmith Odeon in January 1986, are the same as on Brief Encounter, an EP released only in the USA a few months earlier. Accordingly, the title printed on the 12" version was "Welcome To The ‚Garden Party‘ (LIVE)".
