Jermaine Jackson, brother to the late Michael, sings Smile at the Jackson memorial performance. The singer was clearly and understandably shaken, but he did a great job of getting through what must have been a really tough performance for him. The lyrics are an especially good fit for the occasion.
Still of Jermaine Jackson singing ‘Smile’ at the Michael Jackson Memorial.

from all hthe coverage since he died, it seems like Jermaine was the closest to him, so this had to be hard on him.
Janet and the kids were in bits as well (in the video of Paris talking). Wow.
