Within shout of Bedfordshire I reckon, as that's where Ragged Staff are based.
2 companions and I sang at a club for disabled people a couple of weeks ago, and they paid us, which was nice (though not a huge sum) and we all had a great time, which was nicer. So go for it if you love singing and sharing songs with others. Take folk back to the folk, etc.
We are within shout of Bedfordshire, too.
