Two huge marquee tents were erected to house the wedding guests as well as the groom and, well, groom.
The reception was fit for a queen or two - it cost an estimated €1.4 million and featured pink champagne and lamb for 700 guests, served inside two giant white tents erected at John’s Windsor mansion.
Yesterday was the first time Reginald Dwight (aka Elton John) jumped the broom for a groom.
In 1986, when he recorded a song called Don’t Trust That Woman, he married a woman, studio engineer and singer Renate Blauel.
On that occasion the bride sartorially slipped into second place when the multimillionaire dressed up in a heady mix of virginal snow whites and pinks.
Yesterday, Mr and Mr John would have gone unnoticed were it not for the fact the world’s media was invited.
Known for his flashy glasses and flamboyant clothes, the pop diva chose black as the new pink.
Furnish, 43, a Canadian-born filmmaker, and John, 58, have been together for 12 years.
“Being such a high profile couple and the fact that we decided to do it straight away does carry a certain message,” John was quoted as saying before the wedding.
“I’m doing this first and foremost because I want to do it for David and I want to be with David for the rest of my life, but I also want to do it to say that (the civil union law) shouldn’t be something that just sits there in law. It should be embraced,” he said.
Those who attended the wedding included John’s mother, Sheila, his stepfather Fred, and Furnish’s parents, Gladys and Jack.
Among those who attended the knees up last night were Michael Caine, Liz Hurley, Donatella Versace and Claudia Schiffer.
