Question: Who were the members of the English rock duo that released "Only One Woman," a song later covered by the Swedish band Alien?
Context: John Charles Brim (April 10, 1922 – October 1, 2003) was an American Chicago blues guitarist, songwriter and singer.  He wrote and recorded the song "Ice Cream Man" (later covered by the band Van Halen on its first album, by Martin Sexton on his 2001 album, "Live Wide Open", by David Lee Roth on his album "Diamond Dave" and by Swedish band FJK as "Isglasskis"). The Monkeys in the Zoo Have More Fun Than Me is the second studio album of Jape released by Trust Me I'm a Thief Records in 2004.  The album was launched in Dublin's Crawdaddy venue.  Like its predecessor, "Cosmosphere", which was released the previous year, it contains eight tracks.  The album included the single "Floating", a song later covered by Brendan Benson of The Raconteurs and the Belgian bastard pop duo Soulwax during their DJ sets.  "The Monkeys in the Zoo Have More Fun Than Me" was followed by the ten-track Choice Music Prize-winning album "Ritual" which was released in 2008. "The Walls Fell Down" is a second single by the English rock duo The Marbles, Lead vocals by Graham Bonnet it was released in March 1969, and it was written and produced by Barry Gibb, Robin Gibb, Maurice Gibb, of the Bee Gees, and was also produced by Robert Stigwood, it was recorded as a follow-up to "Only One Woman" but did not repeat the success of the previous single. "It's Only Love Doing Its Thing" is a track featured on Barry White's album "The Man".  British soul band Simply Red later covered the song, under the shortened title "It's Only Love", as the lead single for their third studio album, "A New Flame".  The Simply Red cover had its greatest success by charting at number one in Italy.  The song later features in several greatest-hits albums and a ballad collection of the same name, and it remains a live favorite. "(I'm a) One-Woman Man" is a song co-written by American country music artist Johnny Horton and Tillman Franks.  It was originally released as a single by Horton in 1956, whose version peaked at number 7 on the "Billboard" Hot Country Singles chart.  The song was twice recorded by American country music artist George Jones: first released on the album "The Crown Prince of Country Music" retitled "One Woman Man" in 1960, and later as "I'm a One Woman Man" released in November 1988 as the first single from his album "One Woman Man".  It peaked at number 5 on the "Billboard" Hot Country Singles chart in early 1989 and it would be his final Top 10 solo hit.  His final appearance on the Top-10 country singles chart arrived a year later as part of a duet recording with Randy Travis.  In spite of the lack of radio hits as the 1990s dawned Jones remained a popular concert draw for the next two decades and continued to release original recordings into the mid 2000s. Alien is a Swedish rock and metal band formed in Gothenburg in 1986 by guitarist Tony Borg and vocalist Jim Jidhed.  They are best known today for their single "Only One Woman", a cover of a Marbles song, and "Brave New Love", which was featured in the end credits of the 1988 remake of "The Blob". Dive was a Swedish band which consisted of Chris Lancelot (a.k.a. Krister Linder) and Erik Holmberg.  They released three albums.  A fourth album was recorded but not released.  Their debut single was also their biggest commercial success; "Captain Nemo" was later covered by Sarah Brightman on her 1993 album "Dive". The Marbles were an English rock duo that consisted of Graham Bonnet and Trevor Gordon, who operated between 1968 and 1969.  Their only well-known singles were "Only One Woman" and "The Walls Fell Down".  They also became associated with the Bee Gees members Barry, Robin and Maurice Gibb at that time. Jim Jidhed (born February 23, 1963), sometimes known as Jim Willy Jidhed, is a Swedish rock singer.  Jidhed's first major break was as the lead singer for the rock band Alien in the late 1980s with the ballad "Only One Woman".  After that he released his first solo album called "Jim", which included the songs "Wild Young And Free", "Silence is Golden" and "Love Hurts".  Jidhed participated in Melodifestivalen in 1991 with "Kommer du ihåg mig?" , finishing 3rd, and in 1997 where he performed "Charlie", finishing 10th. Easy Action is a Swedish band from Stockholm that was first formed in 1981 by Pelle Almgren (ex-Warhead), Henrik "2 meter" Jermsten (ex-Stoodes), Bosse Belsen (aka Zinny J. Zan of Shotgun Messiah/Kingpin/Zan Clan - drums) and Björne Fröberg (bass, ex-Warhead).  Bosse and Björne quit and were replaced by Ola "Skox" Andersson and drummer Urban "Ubbe" Sundbaum (ex-Lustans Lakejer).  Stranded Records became interested and released the single "Honcho Bongo".  It didn't sell well and when the second single, "Om jag vore kung", also failed the band split up.  Skox and 2 meter formed Psyhedelic Mongo and Pelle Almgren started writing songs instead.  Easy Action was reformed as a glam metal band in 1982 by Kee Marcello and Alex Tyrone (aka Peo Thyrén).  The two played together in the Swedish glam act Noice when they decided to start the ultimate glam rock band, mixing their influences of 1970s glam with a punk/metal attitude.  They met the original singer Bosse Belsen, now named Zinny J. Zan, at the Stockholm rock club Ritz and recorded his vocals on the first demos the very same night.  Later the Noice drummer Fredrik Von Gerber and the guitar player Danny Wilde joined the band.  In 1983 they got signed to the US major label Sire and became the first Swedish band ever to sign a worldwide record deal.
