Jack Cunliffe mobile shop in the 60's

Hi
I think I recall a post from many, many years ago about this but I can't find it. Does anyone remember Jack Cunliffe with a shop in a bus in the 60's. He had "Here he comes" on the front and "There he goes" on the back. I used to live in Billinge Rd just up from Simms Lane End in the early 60's
