The countdown continues for NASCAR’s historic return to Darlington Raceway for the first Labor Day weekend running of the Bojangles’ Southern 500 since 2003. As part of “Bojangles’ Southern 500 Throwback Week on MRN, Presented by S-T-P,” Motor Racing Network programming has featured some of the familiar names that helped make it “The Voice of NASCAR” since first hitting the airwaves in 1970 … including Barney Hall, Ned Jarrett and Jack Arute.

Darlington Raceway’s history is being framed with a series of richly produced feature stories airing on MRN’s weekly shows including “NASCAR U-S-A” this coming Sunday morning. For the broadcast of Sunday’s Bojangles’ Southern 500, theme music from the MRN archive will open the network’s coverage … which kicks off Sunday at 6 p.m. (ET).
