New country music duo Miss Willie Brown will sing the national anthem at the FedEx 400 Benefiting Autism Speaks NASCAR Sprint Cup Series race on May 15th at Dover International Speedway. The appearance comes just two days after the duo wraps up touring with Dierks Bentley on the Jägermeister Country Tour. The girls recently posted a video on their website of a prank they pulled on Dierks when they wrapped his Jeep completely in Saran wrap.
