Absolutely, I'm 39 and can't remember a time when I didn't know about George Formby. If you have seen his face and heard him sing there is little chance you would forget him and bearing in mind his films crop up on British tv every now and again I think most people with some cultural awareness beyond a vary narrow, marketed mainstream would know who he is. I think if you were to compile a top 100 list of British cultural icons of the 20th century he would be on it somewhere. Possibly top 50.
