Being a '60's baby, I also can remember a commercial with kids wearing colorful tunics and bell bottoms singing...
Tang! Tang! Tang, Tang!
Tang! Tang! Tang, Tang!
Do the moon walk like the astronauts
Join the space gang drink your energy Tang.
Tang's for breakfast, lunch or after school
Tang's energizing.... (something, something -- I forgot how the rest of it goes!).
It's amazing how those of us who drank it (my mom bought it every once in a while) have any teeth left.
