Can't remember the last time I heard any singing in English pubs, most traditional Pubs have either been closed down or an in such a bad state that they soon will be. A destruction of what little English culture remains and supported by a so called English Government who are taxing and pricing them out of existence. What music is left is on over loud Juke Boxes, when customers practise an unusual tradition of stuffing them full of money but then sit making as much noise as possible so the music can't be heard

Sorry if that's a depressing reply, but outside the folk clubs English traditional songs are rarely heard in Pubs any more. But If you mean an old style English singalong, look up tratitional pub songs on Google, songs like We'll Meet Again, Roll Out THe Barrell, Goodbyee, My Old Man Said Follow The Van, My Ole Man's A dustman, White Cliffs Of Dover, there are hundreds just lying neglected
