One of the dangers of the theme as opposed to a set SOTM is that people will think they have to do something different to everyone else. That really. Wasn't my intention when I suggested it.Damn, I was going to do MASH, too.
In fact, one of the things I was hoping to see perhaps is that the more experienced players may make their own backing/score/assistance available when they post.
The problem that seemed to be developing with SOTM was that if a particular song wasn't your genre, then people didn't have a go. Looking back at the popular SOTM entries, they were very heavily leant towards the 'standard American Songbook', i.e. when the SOTM was a regular jazz ballad, then it was popular, when it was something different, it wasn't.
With a theme, it's easier to find something that's in your genre I think.
