The "Nashville" stars are putting another stop to their upcoming trek.  The actor-singers are extending their run to four shows with addition of a Philadelphia concert on May 5th.  Tickets go on sale Saturday. 

And interest in the tour seems to be high.  Tickets for the other three dates -- in Chicago; Washington, DC; and New York City -- all sold out quickly. 

The "Nashville" Concert Tour features Clare Bowen and Sam Palladio, who portray Scarlett and Gunnar; Charles Esten, who plays Deacon Claybourne; and Chris Carmack, who's Will Lexington on the show.  Will Chase, "Nashville's" Luke Wheeler, is also part of the New York concert's lineup.
