I was thinking of starting a business where I would solicit sponsorship for buskers to play corporate jingles. It turns out Coke tried to do it in London in 2009 at Christmas and everyone wouldn't stop bitching about it.

Has any good stories of ventures that didn't work out. Shame for people to invest hard work in ideas that don't work out. I'm sure there is an internet website database market analysis thingy commercial viability thingy for this sort of thing already, but I haven't heard of it. And if not...well....I think I just found my next business idea
