Singers also get sick as well. Usher had cancelled his show in Germany because of sickness.  In fact, when he was on one of his shows before all were cancelled, he performed but ended up having lip-synched the songs and dancing poorly. But, fans booed him and after standing on stage for four minutes, he walked off and the crew announced that the show was cancelled because Usher was not feeling well. That’s sad. We hope Usher will get well soon so he can perform his songs and moves to his lovable fans.
