Many of Eurovision's performances have been described as out of this world.
And last year's near-win by Sam Ryder, who sang Space Man, brought the 2023 final to Liverpool.
But Scots singer-songwriter Rikki Peebles was on the trend decades before.
He represented the UK in 1987 with a song inspired by his sighting of a UFO in his home city of Glasgow.
"All my adult life I have had an affinity with all things UFO, not of this world," Peebles said.
"It was about 1984 and I was in my car driving on the new M8 motorway. I sat at a junction after coming off .
"I looked up and I saw this massive light in the sky but it moved from my left, right across my vision to the right and then slowly disappeared.
"I thought I had to report this to authorities. I did and the next day the same thing had been seen over parts of Wales. I knew it wasn't just me. This was something not of this earth."
