Old Man's Beard?

Went for my 3500 step power walk this morning. I am hoping that this excercise will help keep the nasties at bay. Probably a pipe dream but you never know. I always take my camera but I was confident of an unexciting day so wanted to try to photo something interesting early on. I think this is Old Man's Beard. If it is, then apparently it is a type of clematis which likes chalky/ alkaline soil. As we are on the Downs which are definitely chalky, then that would fit nicely.
