Found this video of Mercedes Sosa singing on Mexican television in the 90s.
Lots of things to notice in this video:
- the awful pink and gold ensemble the presenter is wearing
- how Mercedes thinks her mike is not working at the end of song 2, and keeps asking for it to be turned on. She is banging the mike making big gestures - hilarious.
- two awesome songs. The second is my current favourite: Maria Maria by the Brazilian Milton Nascimento. ae -ae-a-ae-ae-ae-e-e-eeee
- La Negra dancing about, moving across the set - a huge difference from her concerts today where she remains sat on a chair. ela she is older now, so it's ok.
