I don't know. Maybe they are having trouble renewing contracts. I would imagine it would difficult to proceed with this show if Connie or Hayden decided to not coninue with the show. I think both of them AND Deacon are intregal parts of the show. It would really suffer if any one of them left. AND it would also be very awkward if either of the sisters who play Connie's daugthers left. Replacing them would be so awkward. And how likely would it be to send them off to boarding school?
Country is music today is very different from country music of even 10 years ago. It's actually more pop, IMO. I love all kinds of music, from Patsy Cline, Hank Williams, Jr., Shania Twain, to Carrie Underwood, Randy Houser, etc.
