Singer Miranda Lambert surprised her fans with a brand new song "Sweet by and by".

The track was recorded by the country superstar for producer Dave Cobb's upcoming compilation album "Southern Family", reports aceshowbiz.com.

In the song, 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 sings and adds in the chorus: "Mama I have not forgotten/ Lessons learned under the light of/ The Southern starry sky."

The "Southern Family" compilation will release on March 18. In addition to Lambert, it features contributions from other country music artistes like Jason Isbell, Zac Brown, Brandy Clark and Chris Stapleton.
