In September 2015, it was announced Squier would call part of the Bojangles' Southern 500 race as part of a throwback weekend for NASCAR to celebrate the years 1970-1974. Squier was joined by Ned Jarrett and his son Dale Jarrett. As part of the deal with Darlington with its throwback theme for the next several years, the trio called part of the race again in 2016 as the years 1975-1984 were celebrated. They returned in the same capacity for 2017. Squier got some media reaction after nicknaming Erik Jones That Jones Boy for his very hot top 5 streak.
