May have been true a few years ago, but these days a big chunk of those attending your typical local soul night are pretty much new to the scene, and have joined because of the social aspect of nights out with people their own age rather than any desire they may have to relive their Yoof'....
Ruby Andrews is the perfect example, ie it may be old, but it's not an oldie as such. It just fits perfectly in todays nice inoffensive 'disco' scene where tracks are popular because of their safe tempo and production, hence why stuff like Sidney Barnes, DJ Genitals, Party Time Man and that hateful Tribute thing fill dance floors up and down the country every week......
