It is awesome that you have posted the Four Step Brothers appearance. My Dad performed with them on that date and never forgot it. His name Was Edward "Prince" Bozeman Jr. We never found any footage or pictures. We would love to have that footage. He remembers being on with soupy sales. He went on performing with them until they retired the group in the 70's. We never found any more footage of Dad on any of the Four Step Brothers pictures. Those were the best days of his life. My Dad has now passed away as the last member of the Four Step Brothers. I believe He came on in 1964. I miss him and still looking for more footage someday.
