Glees I used to work at Mars Confectionery and can confirm that Mars piloted a cake bar called Glees. Unfortunately it required a tiny amount of alcohol in order to remain fresh. When Forest Mars' mother found out that her family company was about to market alcohol to children the product was ditched. Mars owned the name, which had been used for a Skittles-like sweet many years before. Weirdly, Mars' market research discovered that children who were too young to have ever tasted the original sugar Glees still seemed to remember it!
