#20 YouTube

I really enjoy the old commercials - from 60s & 70s. Of course, I also remember going into McDonald's and singing, "Two all beef patties, special sauce, lettuce, cheese, pickles, onions on a sesame seed bun." Workers enjoyed it and once gave a friend a free big mac. I would like to add "Apple Trees and Honey Bees" video from Coke. http://www.youtube.com/watch?v=osSbT5WWsJA. I remember teaching that song in my music class, but without the coke words. Good times. But can I add to my blog without breaking copyright? YouTube could be used for demo purposes for research or a how-to for students when they were working at home.
