Eurovision: How Welsh entrants scored before Bonnie Tyler
The UK has been holding out for a Eurovision hero for a long time and this year hopes rest on Wales' Bonnie Tyler with her song Believe in Me.
The last time the UK won the competition was in 1997 with Katrina and the Waves' Love Shine a Light.
It has been pretty dark since then, with many UK entries failing to trouble the scorers too much.
So as the UK gets behind the Total Eclipse star, BBC Wales' Melanie Lindsell takes a look back at some of the archive footage of Welsh entrants who braved Eurovision before her.
1970 Mary Hopkin - first UK entry from Wales
Those were the days when 19-year-old Mary Hopkin from Pontardawe, in the Swansea Valley, performed Knock, Knock Who's There? and nearly won the 1970 Eurovision Song Contest with 26 points. All Kinds Of Everything by Ireland's Dana won with 32 points.
In March, Knock, Knock Who's There? peaked at number two in the UK chart, and remained among the best sellers for 14 weeks.
Mary Hopkin was born in May 1950 and first found international fame in 1968 through the TV talent show Opportunity Knocks. The folk singer from a Welsh-speaking community won Opportunity Knocks six weeks on the trot, before topping the charts with her debut single, Those Were The Days, which also reached number two in the US.
In 1971 she married the legendary American rock producer Tony Visconti, but they divorced in the early 1980s. They had two children, both now musicians and producers.
Today Hopkin at 63 is living back in Wales, still writing and recording music, but prefers not to perform live anymore. In 2010 she worked with her daughter, Jessica Lee Morgan, on her first CD and also released an album You Look Familiar with her son, Morgan Visconti.
1976 Nicky Stevens - the only Welsh singer to win Eurovision
Brotherhood of Man's Nicky Stevens from Carmarthen is the first, and to date only, Welsh artist to win Eurovision for the UK.
The chart-topping 1976 UK entry Save All Your Kisses for Me is still the most successful Eurovision song and was number one in 33 different countries. In the UK it held the top spot for six weeks.
It sold over six million copies worldwide and remains one of the top 150 selling songs in the UK.
The band celebrated their 40th anniversary in 2012, and Brotherhood of Man's line-up today of Lee Sheridan, Nicky Stevens, Martin Lee and Sandra Stevens remains unchanged.
1990 Emma Louise Booth - becomes Britain's youngest representative
Bridgend's 15-year-old Emma Louise Booth became Britain's youngest Eurovision representative with Give a Little Love Back to the World. It finished in sixth position.
At the time she only narrowly made the newly implemented age rule in the competition, where all contestants must be 16 in the year they compete.
The winning entry came from Italy with their second Eurovision victory: Insieme: 1992, performed by Toto Cutugno.
Jessica Garlick - top UK entrant of the 2000s
Another Welsh Eurovision success was Kidwelly's Jessica Garlick, who finished joint third in 2002.
This making her the highest placed British entrant in the Eurovision Song Contest of the 2000s.
The song, Come Back, went on to reach Number 13 in the UK charts.
The winning entry came from Latvia with I Wanna, by Marie N.
Jessica Julie Anne Garlick was born in 1981 and made her first steps into showbusiness when she was 16. She won the Welsh final of the TV talent show Star For A Night, and in the same year she also featured in Michael Barrymore's My Kind of Music.
After her Eurovision success, she married her childhood sweetheart, Owen Satterley, and they had a daughter Olivia and a son Noah.
Garlick made an attempt in 2009 to relaunch her career, but the album failed to chart.
2004 - James Fox, Hold on to our Love
The last Welsh act to represent the UK at the Eurovision Song Contest in Turkey in 2004, was Cardiff born James Fox . His song 'Hold on to our Love' finished in 16th place.
Ukraine's 'Wild Dances' by Ruslana Lyzhichko' was the winning song .
Fox was born James Richard Mullett on the 6 April 1976 in Cardiff. He grew up in Gilfach, Bargoed in the Rhymney Valley.
His professional career began at age 15 in a rock band touring south Wales working man's clubs.
In 2003, he took part in the BBC's Fame Academy and took the stage name James Fox. He came fifth, but the experience presented him with new career opportunities such as the Eurovision Song Contest.
In 2008 Fox wrote and recorded Cardiff City's FA Cup Final song, "Bluebirds Flying High".
Both his Eurovision entry in 2004 "Hold Onto Our Love", and "Bluebirds Flying High" in 2008 became Top 20 chart hits.
2010 Welshman sings for Cyprus
And finally, although not actually representing the UK, Welsh musician Jon Lilygreen performed at the 2010 competition in Oslo, Norway.
Singing with The Islanders, Newport's Lilygreen, represented Cyprus.
The Islanders had an international line-up with performers from all over Europe.
Cypriot songwriters Nasos Lambrianides and Melis Konstantinou, were led to Wales after surfing the internet in their hunt for a singer to perform 'Life Looks Better in Springtime' .
The song came 21st in the final of the 55th annual Eurovision Song Contest. Lena, representing Germany, was the winning entrant with 'Satellite'.
Lilygreen has since formed a band, Lilygreen & Maguire, a Welsh pop rock duo formed in 2011.
The pair signed with Warner Bros. Records and have since released three singles, Given Up Giving Up, Ain't Love Crazy and Come On Get Higher.
In October 2012 Lilygreen & Maguire supported Scouting For Girls on tour.
