Well, I guess one single 1970's mention of breastfeeding on Sesame Street is one too many for today's merch-pushing execs, at least when it turns back up on YouTube.
The TOU violation's not the same as the notice whens something is removed by a request from the copyright holder, though, so something odd may be going on here. Still, Sainte-Marie's breast deserves its place in history back.
