Called "Sweet By and By", the track was recorded by the country superstar for producer Dave Cobb's upcoming compilation album "Southern Family", reported Ace Showbiz.
Lambert sings about childhood lessons her mother and father taught her.
"Tell the truth/ Earn your dollar/ Let not your heart asunder/ Save yourself/ Believe in faith/ Good things come to those who wait," she coos and adds in the chorus, "Mama I have not forgotten/ Lessons learned under the light of/ The Southern starry sky."
The "Southern Family" compilation is set for release on March 18.
