The rest of the strings look OK, so perhaps I'll just replace the single string for now - the guitar is fairly new (though cheap), but will replace all in a few weeks.
-- Dave, I'll look out for the single string packs. BTW - do you live near Chester? That's where my wife and I got married (Chester Town Hall). Been living in US for 11 years now.
Best,
