Granted, most men used it back in his era, but it seems to me Freddie Trueman always had a LOT of Brylcreem in his hair, & with that sort of 'floppy' hairstyle he sported at one point, was always running his finger through his hair to get it out of the way.

He cant have been the only one, but the more I think about it, the more it seemed that his hairstyle & everything was contrived to enhance that little trick!
