At 4 p.m. Monday, hundreds of Philadelphians, including Mayor Nutter, are expected to gather on the Art Museum steps to try to form the world's longest Soul Train line.
The dance line - an effort to commemorate the life of Soul Train creator Don Cornelius - could break the Guinness record, now held by a Berkeley, Calif., high school, if more than 211 dancers come together.
"We can beat that record," said organizer Mannwell Glenn, 50, of West Philadelphia.
Glenn, a radio host and political consultant, said he expected at least 500 dancers. "Judging by the response on social media, it looks like we're going to have a healthy crowd," he said.
