It would be rude not to

There's an old boy who lives up the road from me. He's lived there as long as I can remember and I've lived in my road on and off since 1962. Yesterday he knocked on my door and told me he'd been given a leaflet at Mill Hill Broadway Station on Wednesday Evening. He said "I voted for you at the last Election. Can you do something for me?" I said "Depends what it is". He said "Put this leaflet on your website". I looked at it and said "It would be rude not to". Here it is.
