The Roots will serve as the house band, but Jimmy Fallon isn't coming.
"He does his own thing on the fourth," Tariq "Blackthought" Trotter said Thursday.
The musical group, which usually serves as the house band for Fallon's late-night talk show, were on hand Thursday as city officials read the lineup for the Wawa Welcome to America! festival.
This year The Roots will be joined by John Mayer, Ne-Yo, Demi Lovato, Ben Taylor, J. Cole, Grace Potter and Jill Scott.
Mayor Michael Nutter billed the event, which will take place on the Benjamin Franklin Parkway on July 4, as "the largest party in America."
Despite requests, Nutter said he wouldn't take the stage.
"I know my limitations," he said.

- "Silver Linings Playbook" to play at Rittenhouse Square at 9 p.m. on July 1.
