Tonight’s episode is the third Nashville special to follow the real-life cast members of this show as they embark on a concert tour. Don’t look for the top female headliners this year, but the participants do include Clare Bowen, Chris Carmack, Charles Esten, Sam Palladio, Aubrey Peeples and Lennon and Maisy Stella. And these concert specials have proven quite popular in the past, so it’s not surprising they’ve become an annual Nashville tradition (the picture here is from last year’s event).
