Chadwick Boseman honored by wife during 'Stand Up to Cancer' event

Boseman's widow performed an emotional rendition of "I'll Be Seeing You."

Taylor Simone Ledward paid musical tribute to her late husband, actor Chadwick Boseman, during Saturday night's "Stand Up to Cancer" event.

Co-host Anthony Anderson introduced Boseman's widow, saying, "Many of us were devastated to learn of Chadwick Boseman's tragic passing after he privately grappled with cancer for several years."

"The world lost an incredible artist and a true hero," he continued. "But before he was a public figure, he was a person like you or me -- a son, a brother, uncle, cousin, friend, colleague, husband."

The "black-ish" star noted that "many of us are all too familiar with the fracture a dearly loved one's passing leaves in the lives of those who love them. Here to perform a song about living with the reality of loss and finding a way forward is Chadwick's wife, Simone."

Ledward then delivered an emotional rendition of "I'll Be Seeing You," the classic song written in 1938 by Sammy Fain and Irving Kahal and recorded by Billie Holiday, Bing Crosby, Frank Sinatra and Nora Jones, among others.

Also taking part in the "Stand Up to Cancer" event were a number of celebrities -- including Boseman's MCU co-stars Danai Gurira, Chris Evans, Karen Gillan and Paul Rudd.

Reese Witherspoon and husband Jim Toth were the executive producers of this year's event, an annual fundraiser for cancer research and treatments.
