Lady Antebellum played a private show in Nashville last week previewing some new songs, including their latest hit, "Downtown." The group invited the song's writers -- Shane McAnally , Luke Laird and Natalie Hemby -- onstage to help them sing the song, which they jokingly call "Downtown Abbey," a nod to the hit PBS period drama Downton Abbey .

You can check out Lady Antebellum's fun group performance of "Downtown" on the latest installment of Lady A Television . Their new album, Golden , comes out May 7.
