"Last of the Cowboys" was written by Robby Hopkins, Tony Justice, Jeff Silvey and Cody Purvis.  It was melodically based on a song Robby wrote called "You Ain't No Cowboy". 

When Robby opened for Gene Watson the first time at the Tivoli Theatre in Chattanooga, it was shortly after the death of George Jones.  Gene Watson's team asked Robby to cover a George Jones song.  Here's "Who's Gonna Fill Their Shoes"

Robby wrote "Charlie" based on a true story about a man he knew growing up in the northwest Georgia area.

"Comin' Over Sober" performed by Jared Hovis was written by Robby Hopkins, Jared Hovis, and Ben Chapman
