Everybody Loves a Happy Ending

"Closest Thing to Heaven" is a song by the British band Tears for Fears.
 It was released as the first single from their 2004 album "Everybody Loves a Happy Ending", and is the first single that features both original members Roland Orzabal and Curt Smith since 1990.
Charlie Harper (born David Charles Perez, 25 May 1944, Hackney, London) is a British singer and songwriter.
 He is best known as the lead singer from the punk band U.K. Subs.
The English pop-rock band Tears for Fears have released six studio albums, along with numerous singles, compilations and videos.
 Formed in 1981 by Roland Orzabal and Curt Smith, the duo signed to Phonogram Records in the UK and released their first single the same year.
 It was not until Tears For Fears’ third single, “Mad World” (1982), that they scored their first hit, and their platinum-selling debut album "The Hurting" (1983) was a UK number one.
Raoul and the Kings of Spain is the fifth studio album by the British pop-rock band Tears for Fears, released on 10 October 1995.
 Like the band's previous album, "Elemental" (1993), it is essentially a solo effort by Roland Orzabal—neither album being made with the involvement of Curt Smith, who had left the band at that time.
"Suffer the Children" is a song by the British band Tears for Fears.
 Written and sung by Roland Orzabal and released in November 1981, it was the band's first release, recorded in Bath, England shortly after the break-up of Orzabal and Curt Smith's previous band Graduate.
 The song would eventually be re-recorded for inclusion on Tears for Fears' debut LP "The Hurting" (1983).
Tomcats Screaming Outside is the first solo album from British musician Roland Orzabal of the group Tears for Fears, and was released on 2 April 2001.
 Although Orzabal had effectively made two solo albums under the Tears for Fears moniker in the 1990s (following the departure of bandmate Curt Smith), this was the first recording to be released under his own name.
 This album was Orzabal's last to feature contributions from Alan Griffiths, who co-wrote most of the tracks on this album as well as the previous two Tears for Fears albums.
 The album was given a low-key release and did not chart, but earned some critical acclaim for its clever melding of pop songwriting and drum 'n bass, ambient techno and trip hop textures.
 Dan Gennoe claimed in Amazon.com's editorial review: "Solo album or not, "Tomcats Screaming Outside" is the best Tears for Fears album in a decade."
"Shout" is a song by British band Tears for Fears, written by Roland Orzabal and Ian Stanley and sung by Orzabal (with Curt Smith duetting on the chorus).
 First released in the UK on 23 November 1984, it was the band's eighth single release (the second taken from their second album "Songs from the Big Chair") and sixth UK Top 40 hit, peaking at no. 4 in January 1985.
 In the US, it reached no. 1 on the "Billboard" Hot 100 on 3 August 1985 and remained there for three weeks.
 "Shout" would become one of the most successful songs of 1985, eventually reaching the Top Ten in 25 countries.
 "Shout" is regarded as one of the most recognisable songs from the mid-eighties and is also recognised as the group's signature song, along with "Everybody Wants to Rule the World".
Curt Smith (born 24 June 1961) is an English musician.
 He is best known for forming the band Tears for Fears, along with childhood friend Roland Orzabal.
 As a solo artist, he has released four solo albums.
"Change" is a song by the British band Tears for Fears.
 Written by Roland Orzabal and sung by bassist Curt Smith, it was the band's fourth single release.
 It would eventually become the second hit from their debut LP "The Hurting" (1983) and second UK Top 5 chart hit, following the success of "Mad World".
 The song also gave Tears for Fears their first charting single in the United States when it cracked the "Billboard" Top 100 in August 1983.
 "Change" was also a big international success, reaching the Top 40 in numerous countries.
Everybody Loves a Happy Ending is the sixth studio album by the British pop-rock band Tears for Fears, released on 14 September 2004 in the US, and 7 March 2005 in the UK and Europe.
 It was released some nine years after the previous Tears for Fears studio album, "Raoul and the Kings of Spain" (1995), and was the first album featuring both original bandmembers Roland Orzabal and Curt Smith together since 1989's "The Seeds of Love".
