Think about this….

From the White House Blog:

President Barack Obama led a Kennedy Center crowd in a performance of “Happy Birthday,” capping a star-studded musical birthday tribute to ailing Sen. Edward M. Kennedy.

The Massachusetts Democrat was honored at the Kennedy Center at an event Sunday night hosted by comedian Bill Cosby. Actresses Lauren Bacall and Bernadette Peters, singer James Taylor and conductor John Williams were among those who performed.

My question is, who did John Williams conduct? Or what did he perform? From what’s written here (where I ended was the end of the paragraph about performers), it looks like ol’ John got up on stage and conducted as his performance…maybe with no one being conducted. I find it quite a funny mental image…
