We take it in turns to lead a song, going round the room. Plenty of choruses, and you'll soon get used to figuring out where to join in. You don't have to lead a song, you're welcome to join in the choruses. Many of the songs are old/traditional, but that's not the primary reason we sing them - they've lasted because they're so good to sing in good company! Brilliant accoustics, great range of drinks, pub snacks, excellent company - what more could you ask for?
