I'm guessing these have been posted. But they are two of the most tragic televised performances I can remember in recent years.
First is Iggy on Dancing with the Stars:

And second is American Authors from an Oscars after party I believe:

No shade to either artist. But the American Authors performance is one of the worst I've ever heard/seen. He's off key the whole time. The back up vocals are even more off key. And some of the band is playing a few beats behind the rest of the band

This was the only performance I could find left on YouTube. I'm assuming they took them all down because it was so tragic. I felt so bad after it happened too
