I always thought it was funny how "Hall of the Mountain King" and "Joshua Fit the Battle of Jericho" sound so much alike. The sample is clearly Joshua.
The commercial was, "Can't get enough of that Sugar Crisp, Sugar Crisp, Sugar Crisp, an't get enough of that Sugar Crisp, it keeps me going strong" using the tune to Joshua. That was back when you could still call a cereal something with sugar in it. Now I guess it's Super Golden Crisp or something like that...Do they still call the character Sugar Bear or did they change that, too?
