Singing should be fun for the performers, as well as the audience. I prefer people singing in their own accent, however tame that may be, rather than a mid-Atlantic or MacColl’s ridiculous Hoots Mon accent, but it’s tricky to do and what’s the option? Barring people from joining in?

Music doesn’t have to be devastatingly original and authentic, every time. Most of the time, it’s just for fun, after all.
