Veteran crooner Humperdinck, nicknamed The Hump, opened the show in Baku, Azerbaijan with ballad Love Will Set You Free as he represented the UK.
However he seemed to have been forgotten by the time the voting started 25 songs later, racking up just 12 points to finish second-last ahead of Norway.
Meanwhile Irish twins John and Edward Grimes - otherwise known as Jedward - finished in nineteenth place despite a typically energetic performance.
The former X Factor contestants sang Waterline, ending their performance by jumping into a fountain on the stage.
A score of 46 on Saturday night ensured the pop duo were not able to repeat or improve on their Eurovision debut in 2011, when they sang Lipstick.
But the boys thanked their fans on Twitter for their support.
The runaway winner of the competition was Swedish singer Loreen, who racked up an impressive 372 point tally with dance track Euphoria.
She was an early favourite and took top marks from several nations. Speaking after the win, she said: "I want to say that I love you so much. Thank you for believing in me."
Humperdinck congratulated her and said he had enjoyed his Eurovision experience.
"I've had many highs in my career and Eurovision has been a wonderful experience," said the 76-year-old. "I did the best for my country, the rest was out of my hands."
"I want to thank everybody, especially my fans around the world for their words of support."
However questions will be asked following one of the UK's worst outcomes at the song contest.
Previously the public could decide the singer and song that would represent the country, but that was scrapped in 2011.
Then boy-band Blue performed I Can and finished eleventh.
The UK last won the competition in 1997 when Katrina And The Waves - fronted by American singer Katrina Leskanich - took the honours with Love Shine A Light.
Celebrities gave their opinions on the night's performances on Twitter.
TV presenter Phillip Schofield was asked by a fan if it was time to bring back the public vote to choose the UK act, but replied: "Nope, it's time to pull out."
