They could have just as easily picked more modern (and by modern I mean 20-40 year old songs that are already classics) country music and had the same effect. Imagine Trixie belting out “Jolene,” Shaker doing “All my Exes live in Texas” or Earnest doing “Calling Baton Rouge.” Big Al would of course sing “Blood on the Saddle” because you dont mess with perfection. I would also borrow from Vacation Hoedown and do “Rocky Top” and “Thank God I’m a Country Bear” with Bear Band Serenade and Come Again staying as well.
