Since its inception back in 1956, the Eurovision Song Contest has featured dozens of languages, with the rules changing over time on what languages can be used for songs.
Prior to 1966, countries could perform in whatever language they chose, until the rules changed so that countries had to sing in one of the country's official languages, though this was abolished from 1972 until 1977, and then abolished again in 1998.
As such, English is by far the most common language chosen by winners.
Dave Benton won Eurovision for Estonia before he could even speak Estonian.
Performing the song 'Everybody' alongside rock singer Tanel Padar and boyband 2XL, they were victorious in 2001 in Copenhagen, receiving 198 points.
The first of two Olsens to make this list following their win with 'Fly on the Wings of Love', older brother Jorgen became Eurovision's oldest victor in Stockholm in 2000.
He would only hold onto the record for a year due to Dave Benton's aforementioned triumph.
As a consolation, the combined ages of The Olsen Brothers mean that they technically are the oldest aged act to win the Eurovision song contest.
Italian pop sensation Toto Cutogno was, at one point, the oldest winner of Eurovision.
1990's winner in Zagreb, he broke the 32-year-old record with his composition 'Insieme:1992', which celebrated political integration across Europe and the creation of the EU.
Digging into the Eurovision archives, Andre Cleveau was victorious in 1958 with 'Dors, mon amour', and was the only winner to be in their forties before 1990.
The younger Olsen brother rounds out the top five.
The pair are Eurovision icons and were nominated amongst the 14 finalists in 2005's 'Congratulations: 50 Years of the Eurovision Song Contest', where they finished sixth.
Emil Ramsauer became the oldest Eurovision contestant by some distance when he played the bass for Swiss act Takasa in 2013.
There was a huge age range amongst the band, as lead singer Sarah Breiter was 22 when they performed in Malmo.
Buranovskiye Babushki captured the hearts of Europe when performing and finishing second in Baku, back in 2012.
The word babushki translates to "grandmothers" or "old women" in English, with Natalya Pugacheva making this list as the oldest of the bunch.
Remarkably, the UK's Engelbert Humperdinck wasn't the oldest contestant in his year's Eurovision lineup, as he also featured in Baku in 2012.
Missing out on second by a matter of months, Humperdinck was selected because the United Kingdom wanted a legend to represent them in the competition, though he could only manage a 25th placed finish - out of 26 contestants.
Croatian artist Ladislav Demeterffy, more commonly known as 75 Cents, performed 'Romanca' with the band Kraljevi ulice in Belgrade.
At the time in 2008, he became the oldest contestant in history, but has seen his name slide down the list through the years.
No prizes for guessing the inspirations for his stage name.
German singer Lale Andersen represented West Germany in 1961 with the song 'Einmal sehen wir uns wieder'.
She held the record for the oldest Eurovision entrant for over 45 years until 75 Cents snatched the crown in 2008.
