I think you are right about Pledge, but it's obviously not the answer they are looking for if you need the consecutive letters NCH. Some other product must have had the same slogan.
Thankyou kettle drum - I think I must have confused you with the Pledge question - it should have had the heading Pendleside Quiz - it was nothing to do with the NCH quiz _ sorry
I'm also a bit confused about the place between Godmanchester & Coxbench.....Is that Dunchurch (right general direction), or are we looking for a second place?
