Wild Flower - Identitiy Unknown

These flowers are growing along the path down to the river and along the riverside. What actually attracted me to them was their hairy stems which down by the riverside were backlit. Its almost as thought they were glowing.

I spent some time trying to identify them on the net but failed to do so. I must remember to bring examples back with me when I am unsure of their identity. Meantime I am hoping my blip friends can help me. Definitely worth seeing LARGE just to see the detail on the stems. By the way if any of you have useful tips re identification sites for wild flowerws I wold be grateful to hear from you.

Its seems that this flower is probably red campion.
