Siedah Garrett -- the Grammy-winning and Oscar-nominated songwriter behind hits from Michael Jackson, Aretha Franklin, Jennifer Hudson, will.i.am and more -- is joining Chicago on the entertainment lineup for Nancy Davis' 24th annual Race to Erase MS gala. Garrett will sing her new single “Carry On” for invited guests, including Larry King, Sarah Paulson, Kathy Griffin, Randy Jackson, Lance Bass and New Girl’s Max Greenfield at the Beverly Hilton on May 5.

Garrett, who has been nominated for best original song at the Oscars twice, for songs from Rio and Dreamgirls, said she was inspired to write her new song after meeting Davis and learning of her dedication to finding a cure for MS. Davis’ gala has raised more than $46 million toward researching and curing MS -- a disease that Davis was diagnosed with more than 20 years ago.

“I’ve always embraced the opportunity to use my God-given talent as a lyricist to support social causes and charities, and encourage others to do the same,” Garrett said in a statement. “With MS, for me it’s very personal, in that someone close to me is fighting the disease. If my songs in some small way can make a difference, then I’ll keep on writing.”

Garrett also currently has released her single "G.H.E.T.T.O." (Greatness Happens Even Though There’s Oppression) featuring Common.

The gala has previously featured performances by Elton John, KISS, Stevie Wonder, Aerosmith, CeeLo Green, Natalie Cole, Steven Tyler, Ne-Yo and Rita Ora. This year’s event will honor Sopranos alum Jamie-Lynn Sigler with the Medal of Hope award for her battle against multiple sclerosis for the past 15 years.

Funds raised from the event will go toward the Center Without Walls program established to bring together top doctors to find a cure for MS.
