The One America Appeal has already raised $31 million ahead of the concert for relief efforts in Texas, Florida, Puerto Rico, and the U.S. Virgin Islands following the devastating hurricanes.

The rest of the line-up included legendary country performers like Lyle Lovett, Robert Earl Keen and Alabama along with Rock and Roll Hall of Fame singer Sam Moore.
