Something あなた didn't know about Michael Jackson before his death...

Michael Jackson died in 25th June. The 日 before, 24th June he had a main practice in Staples Center for the コンサート tour in London. People who saw him there, 発言しました that Michael has never danced and singed better than now. He even beated the young background singers/dancers. There was nothing wrong with him. This was a huge shock for them when they heard that he died a 日 later.
Did this surprised you? Were あなた shocked too?
