Eurovision: Celine Dion, ABBA, Julio Iglesias, and other famous performers
Much of the time the Eurovision Song Contest features performers who might be stars in their native countries but are unknown internationally.
Winning the contest can sometimes lead to performers becoming household names, however, and occasionally a big star will take the plunge and leave themselves at the mercy of the juries and Europe's TV-voting public.
Here are six people who either made it big because of Eurovision, or made it big and then did Eurovision.
Lulu, United Kingdom: Boom Bang-a-Bang (1969)
The pint-sized Lulu was the second Scottish performer to represent the UK in four years when she sang Boom Bang-a-Bang in 1969 — and the contrast was stunning.
In 1966, the classically-trained Kenneth McKellar had drawn gasps from the audience in Luxembourg as he appeared on stage in a kilt to sing the rather downbeat ballad A Man Without Love. His ninth-placing was the UK's worst-ever performance at the time.
Lulu came into the 1969 contest as an internationally known star, thanks to her role in the film To Sir With Love and her release of the title song which reached number one in the US.
The thrust of the up-tempo love song was immediately clear: "My heart goes / Boom Bang-a-Bang, Boom Bang-a-Bang / When you are near."
On stage in Madrid, she nailed her performance and even threw in an "Ole" at the end, which drew big applause in the hall. She shared her win after the vagaries of the voting system led to a four-way tie.
Julio Iglesias, Spain: Gwendolyne (1970)
Before there was Enrique Iglesias, his dad Julio sold his fair share of music as well.
The original Latin crooner's debut album had proved popular in Spain, leading to his selection for Eurovision in 1970, singing his own composition Gwendolyne.
Perhaps he thought he was singing for Ireland, as he emerged in a suit featuring enough green to stand out on St Patrick's Day before emoting his way through a Spanish paean to lost love.
It does not quite compare to his later hits like To All The Girls I've Loved Before, but it was still good enough for equal-fourth place behind Irish winner Dana, singing All Kinds Of Everything.
He went on to sell more than 100 million albums worldwide.
Cliff Richard, United Kingdom: Congratulations (1968), Power To All Our Friends (1973)
For famous performers, one Eurovision is usually enough — if they win, they move on to other things, and if they don't, a return to the contest is unlikely to be on the agenda.
Cliff Richard sang twice for the UK — in 1968 he was the hot favourite, singing Congratulations, only to lose by a point to Spain's Massiel, whose song La, La, La repeated the same word no less than 123 times.
Justifiably frustrated by the experience, the British pop star was somehow persuaded to go again in 1973 with the public's choice, Power To All Our Friends.
He had taken valium to overcome nerves, and his manager struggled to wake him up before the performance.
Richard sang it well, but his on-stage choreography left a lot to be desired — his thrusting arms and wobbling legs made him look like a cartoon character, and he nearly fell over attempting a 360-degree spin near the end of the song.
He had to settle for third place behind the winner Anne-Marie David, who sang Tu Te Reconnaitras for Luxembourg.
ABBA, Sweden: Waterloo (1974)
If you haven't heard of this one, you just haven't been trying, or you've recently emerged from a few decades in a cave.
In a nutshell: Swedish band, orchestral pop sound, decent singers, futuristic guitars, mad costumes — a perfect storm for Eurovision.
After missing out on the contest the previous year with Ring Ring, ABBA came back with another cracking song that had the crowd in Brighton (the UK was hosting because 1973 winner Luxembourg couldn't afford it) rocking in the aisles.
From conductor Sven-Olof Walldoff sauntering out in full Napoleonic costume, to the fantastic foursome's glitter-glam look to the flat-out best song on the night, it was a clear winner.
ABBA — and Eurovision — never looked back.
Olivia Newton-John, United Kingdom: Long Live Love (1974)
Plenty of Australians have performed at Eurovision, including Gina G for the United Kingdom in 1996, and Johnny Logan (AKA Sean Sherrard from Frankston) who won twice for Ireland in 1980 and 1987 and wrote the winner in 1992.
But the most famous Aussie at Eurovision was Olivia Newton-John, who was chosen as the UK's singer for 1974. The British public selected the cheerful, if naff, Long Live Love as her song.
Sadly her outfit was a shocker — in a ruffles-heavy blue number, she looked less like Sandy from Grease and more like Little Bo Peep without the bonnet and the crook.
The luck of the draw meant she was saddled with the so-called "curse of number two". No song has ever won Eurovision before or since after being sung second in the running order.
Despite the poor portents, she finished in a respectable fourth place behind ABBA.
Celine Dion, Switzerland: Ne Partez Pas Sans Moi (1988)
Long before she ever broke the worldwide music charts with My Heart Will Go On, Celine Dion made it big with her performance at Eurovision.
As befits a Canadian songstress, Dion sang in French at the 1988 contest in Dublin, representing not France but Switzerland.
Ne Partez Pas Sans Moi (Don't Leave Without Me) was perfectly in her musical wheelhouse — a trademark Eurovision power ballad with a couple of rising key changes and a finish that could smash glass.
Of more interest to students of the contest, however, is the question of how on Earth she agreed to wear one of the worst outfits ever seen at Eurovision, a white/gold combination skirt suit with added ruches.
Despite her fashion faux pas, she won the contest by a single point from the United Kingdom's Scott Fitzgerald, singing Go.
