Listen to Megadeth on iHeartRadio

Megadeth's Dave Mustaine admits his band's inclusion in the George Jones tribute concert raised some eyebrows. 

But before the show the rocker told Nashville's Fox 17 they were there for a simple and obvious reason - to honor the late country legend.  And he said his group chose to do so by "honoring his beliefs." 

Mustaine explained that Jones championed America's veterans, and highlighted the treatment of Vietnam vets in his song "Wild Irish Rose," which was the song Megadeth chose to perform at the event. 

The band teamed up with singer-songwriter Jamey Johnson for the lengthy event, which ran nearly four hours. 

A few other non-country artists took part in the concert as well, including R&B great Sam Moore, while says Styx frontman Tommy Shaw provided a highlight with his rendition of Jones' "She Thinks I Still Care." 

More than 100 artists took part in the show, including country legends Alan Jackson, George Strait, and Garth Brooks. 

"Playin' Possum! The Final No Show" took place at Nashville's Bridgestone Arena Friday night.
