Thanks for that, Barbara!
Wow, that brings back memories.
1985. I was 15 years old when Live Aid happened in my home city of Philadelphia.
I fixed the embedding.
You didn't do anything wrong, it was the YouTube link that was messed up.
Sometimes YouTube doesn't give a correct link in the address bar at the top and adds a bunch of other crap for some reason. It's annoying, but I just play the video, then go to my history and click the video again and that usually fixes it.
