One embarassing moment happened while doing a wedding ceilidh in the Assembly Rooms, Newcastle on Tyne. It was a cowboy themed wedding with around 250 guests dressed as Cowboys, Indians, Gamblers and Saloon Girls. I usually start by demonstrating how to swing your partner and try to pick an attractive girl to demonstrate with me so on this night I chose a saloon girl with a low cut clevage. When I asked her to dance she said straight into my radio mike in the broadest Geordie accent
"Y'll hev te watch oot in case me tits drop oot"
I answered that I had been watching all night in case they did. When I eventually got her into a swing they did drop out and I was the only one who missed it as my head was over her shoulder at the time.
Then there was the time we did a ceilidh in a marquee and in the middle of the intro a dog ambled into the middle of the lawned dance floor and dug up a bone and then buggered off.
