The 1989 FA Cup Final was the final of the 1988–89 FA Cup, the top football knockout competition in England.
 The match was a Merseyside derby between Liverpool and Everton, played at Wembley Stadium, London, on 20 May 1989.
 Liverpool won 3–2 after extra time, with goals from John Aldridge and two from Ian Rush.
 Stuart McCall scored both Everton goals.
 The final was played only five weeks after the Hillsborough disaster, in which 96 Liverpool fans were killed in a crush, and before kick-off there was a minute's silence and the teams wore black armbands as a sign of respect.
 Gerry Marsden, lead singer of Gerry & the Pacemakers, led the crowd in a rendition of his hit "You'll Never Walk Alone", which had become synonymous with Liverpool Football Club.
Best of Both Worlds is a two-disc compilation album by British neo-progressive rock band Marillion released in 1997 by EMI Records, who the band had been signed to from their debut in 1982 until being dropped in 1995.
 The title refers to Marillion's two distinct "eras" with lead singers Fish (1980—1988) and Steve Hogarth (since 1989).
 By the time this compilation was released, both line-ups had recorded four studio albums each.
 The second best-of since the 14-track one-disc compilation "A Singles Collection" (known as "Six of One, Half a Dozen of the Other "in the US) from 1992, this one additionally contains material from "Brave "(1994) and "Afraid of Sunlight" (1996).
 Two different covers were created for the compilation, one by Mark Wilkinson, who had worked for the band during the Fish years, and one by Bill Smith Studio, who took over after Fish's and Wilkinson's departure.
 The booklet was printed so that either of the covers could be displayed in the jewel case according to personal preference.
 The track list, comprising 29 songs, was put together by Lucy Jordache, then the manager responsible for the band in EMI, in close collaboration with the band's fans' mailing list, "Freaks" (named after the eponymous song).
 Jordache also motivated singers Fish and Hogarth to contribute liner notes—at a time when both camps were not yet on friendly terms again—by telling each of them the other had already agreed to do so.
Less Is More is an acoustic music studio album by Marillion, released on the band's own label on 2 October 2009.
 A retail version is distributed by Edel Music.
 It contains re-arranged songs from the period that Steve Hogarth has been their singer (since 1989) plus the previously unreleased track, "It's Not Your Fault".
 Despite some positive reviews, the album did not chart in the UK.
"Ferry Cross the Mersey" (sometimes written Ferry 'Cross the Mersey) is a song written by Gerry Marsden.
 It was first recorded by his band Gerry and the Pacemakers and released in late 1964 in the UK and in 1965 in the United States.
 It was a hit on both sides of the Atlantic, reaching number six in the United States and number eight in the UK.
 The song is from the film of the same name and was released on its soundtrack album.
 In the mid-1990s a musical theatre production also titled "Ferry Cross the Mersey" related Gerry Marsden's Merseybeat days; it premiered in Liverpool and played in the UK, Australia, and Canada.
"I Like It" is the second single by Liverpudlian band Gerry and the Pacemakers.
 Like Gerry Marsden's first number one, it was written by Mitch Murray.
 The song reached number one in the UK Singles Chart on 20 June 1963, where it stayed for four weeks.
 It reached No. 17 in the American charts in 1964.
Easter is a song from English neo-progressive rock band Marillion's 1989 album "Seasons End", which became a UK Top 40 hit when issued as a single in 1990.
 Allmusic describe the song as "heartfelt" with an "imaginative electric-acoustic arrangement".
 As with many Marillion songs, the album version features an extended guitar solo by Steve Rothery, which has become a fan-favourite, although it is heavily edited for the single version.
 The song was written by singer Steve Hogarth before he joined the band in 1989 and was inspired by The Troubles in Northern Ireland.
 The title is in reference to Easter 1916 by William Butler Yeats.
 Portions of the video were filmed on the Giants Causeway.
"Don't Let the Sun Catch You Crying" is a song written and originally performed by British beat group Gerry and the Pacemakers.
 The songwriting is credited to Gerry Marsden and the other band members, Freddie Marsden, Les Chadwick and Les Maguire.
 It was first recorded by Louise Cordet, and then recorded by the group themselves in early 1964.
Steve Hogarth (born on 14 May 1956 in Kendal, Westmorland) also known as "h", is an English singer-songwriter and musician.
 Since 1989 he has been the lead vocalist and occasional keyboardist/guitarist with the British rock band Marillion.
 Hogarth was formerly a keyboard player and co-lead vocalist with The Europeans and vocalist with How We Live.
 AllMusic has described Hogarth as having a "unique, expressive voice" with "flexible range and beautiful phrasing".
Gerard Marsden MBE (born 24 September 1942) is an English musician and television personality, best known for being leader of the British Merseybeat band Gerry and the Pacemakers.
A Singles Collection (released as Six of One, Half-Dozen of the Other in the U.S.) is a compilation album of Marillion singles from both the Fish era and the Steve Hogarth era, celebrating the band's ten year jubilee (taking 1982, when their debut single was released, as the starting point).
 It includes the band's six most successful singles of the Fish era, plus all six Steve Hogarth singles up to that year.
 The tracks on it are not ordered chronologically, unlike on the later compilations "The Best of Both Worlds" (1997) and "The Best of Marillion" (2003) that likewise cover both vocalists' eras.
 Additionally, it contains two new recordings with Hogarth on vocals, "I Will Walk On Water" and a cover version of the Rare Bird song "Sympathy".
 This was also released as a single, which peaked at no. 16 in the UK Singles Chart (May 1992), making it the band's highest charting single between 1987 and 2004.
 In August 1992, "No One Can", a re-packaged version of the August 1991 single from "Holidays in Eden", was released as the second single, peaking at no. 26 (original version no. 33).
