Some NASCAR fans did a double take on Sunday afternoon during the performance of the national anthem thanks to saxophonist Mike Phillips and pianist West Byrd.

The two legendary musicians were tasked with playing the national anthem and did a phenomenal job, producing a gorgeous rendition of the tune ahead of the NASCAR Cup Series race at Pocono Raceway.

But shortly after, social media was flooded with Black NASCAR fans who noticed that before and after the national anthem was played, Phillips and Byrd slipped in a few chords from the Black national anthem, "Lift Every Voice and Sing."
