I haven't found this posted anywhere, but I also did not do a comprehensive search, so forgive me if it's already been addressed. I've been watching SANFORD AND SON on broadcast TV and I am amazed at how often Redd Foxx, i.e. Fred, is singing a popular song as he putters around the house. Sometimes he'll sing 2-3 different ones in the same episode. I know that other DVDs have had to be edited whenever a character has sung or even quoted a song where the rights have not been paid for, so does anyone know how the DVDs for SANFORD AND SON have handled this?
