Guest speaker Andrew Curry cheerfully admitted his first entrepreneurial effort had been renting out porn magazines at school. Edinburgh herbalist Dee Atkinson revealed she had been thrown out of Sumatra for an undisclosed indiscretion early in her career.
By the time Curry stopped singing the praises of his company's single malt whiskies, and Atkinson had owned up to a liking for frequenting clubs dressed in leather, the 400 "young achievers" must have been wondering what kind of weekend lay in store for them in the city of culture.
One group of YES persons was not prepared to be outdone. Asked to report on how they went about designing and building a construction on the theme of "inspiration and aspiration" - and to promote the contribution of YES - one presenter invited the conference to admire his "erection".
He kept this up in similar vein for the required 90 seconds, but missed a golden opportunity by not leading the audience in an ecstatic chorus of "YES, YES, YES" at the climax of his presentation.
Small wonder conference chairman John Allcot suggested that when the delegates went home they should perhaps refrain from revealing too much detail. Small wonder, too, that some would-be entrepreneurs were out on the town until 3.30am.
