Saw this today, and it made my Wednesday just a little cooler. Willie Nelson and his sons Micah and Lukas perform a stellar acoustic cover of Pearl Jam's "Just Breathe."

The song was originally sung by Pearl Jam, but was covered by Willie and his son Lukas and included on Willie's 2012 album, "Heroes." The album features quite a few guests, including Merle Haggard, Snoop Dogg, Sheryl Crow and Lukas Nelson. Released in 2012, it peaked at No. 4 on the Billboard Top Country Albums chart.

Watch Pearl Jam do the song, below, back in 2009 at Austin City Limits.
