Johnny Flynn & The Sussex Wit (great name!) are a folk rock band with some catchy songs. It appears that folk is coming back into fashion in the UK, crossing over in the mainstream pop market should not be too difficult.
I can imagine that this band would have the same effect on audiences as Mumford & Sons do, from what I have experienced anyway!
… Coincidentally I just looked at tour dates and they are supporting Mumford & Sons in Europe in the next few months.
They are touring the UK in May – I think I shall go along, coming?
