Skiffle Group
August 1957, and some sort of street fair in Soho, with a skiffle group playing in the street - you can tell it's skiffle because someone is playing a tea chest.
Even if you wanted one and could afford one, you weren't allowed to use a proper bass - it had to be the piece of string attached to a tea chest. It's in the rules of the International Skiffle Federation - look it up if you don't believe me....
