Too Cold At Home was written by Bobby Harden and recorded by two major country country artists, George Jones and Mark Chesnutt. I've done a video on each version so you can compare/contrast the piano fills.
You will find more similarities than differences.
This video covers the George Jones' version of the song. There are more single-line fills in this version than in Chesnutt's. And both make use of the parallel sixths.
