An all-star cast of musicians came together recently to record a cover honoring Tom Petty‘s final song release, “For Real,” a posthumous single that seemed to sum up his legendary career in a voice and a lyric that he could uniquely inhabit. This version is quite worthy of your attention given the group that came together for this.

The legendary Willie Nelson is joined by his sons Micah and Lukas Nelson as well as a few other famous sons, namely Dhani Harrison and Jakob Dylan, and they all pair up with Amos Lee for the song.
