"Ain't No Grave" is not just another one of WWE's theme songs. And it was not sung by Jim Johnston, nor Downstait. This song has a much bigger legacy, as good as those other bands are, to represent a much more iconic man.

You see, "Ain't No Grave" is by Johnny Cash, who, at a much a deeper glance, has many similarities to the man his song now represents eight years after his death.

When I hear that trumpet sound I'm gonna rise right out of the ground

Ain't no grave can hold my body down

Cash's "Ain't No Grave" was released on February 23, 2010. Johnny Cash recorded this song just months before dying, something that he knew was coming. The same can be said for some of Cash's other songs, such as "Hurt."

Well, look way down the river, what do you think I see?

I see a band of angels and they're coming after me



Mark Calaway, better known as The Undertaker in World Wrestling Entertainment, switched this to his theme song before WrestleMania 27. Undertaker, similar to Cash, realizes that his much-idolized career will soon be ending.

Many think of Johnny Cash as a country music singer, but he was not. He transcended barriers, also singing rock, pop music and many other genres.

He didn't care what kind of music it was, Cash was simply an artist with a paintbrush in his hand—nothing else.

Well, look down yonder Gabriel, put your feet on the land and see

But Gabriel don't you blow your trumpet 'til you hear it from me

In comparison, the same is true for The Undertaker. He played both face and heel, played a dead man and a badass biker dude.

Mark Calaway is a man that is looking to tell a story. From his legendary matches with Shawn Michaels, to his bouts with kayfabe brother Kane, all of 'Taker's matches have told a different story.

Cash grew to be an outlaw early on in his career.

His truck once caught on fire, causing 508 acres of a forest to be destroyed. When asked why it happened, Cash responded, "I didn't do it, my truck did, and it's dead, so you can't question it."

On another occasion, Cash was arrested for picking flowers from a private property. He ended up spending the night in jail, inspiring the song "Starkville CIty Jail."

Well, meet me Jesus, meet me. Meet me in the middle of the air

And if these wings don't fail me I will meet you anywhere

Ironically, after "Ain't No Grave" became his theme, Undertaker has been nicknamed The Last Outlaw.

This symbolizes that The Undertaker is the last of his kind. After he retires, the old school era will officially have passed.

In 1968, Johnny Cash married fellow singer and song writer June Carter Cash. The two stayed together until 2003, when June died just a week before her husband.

Well, meet me mother and father, meet me down the river road

And momma you know that I'll be there when I check in my load

Mark Calaway married fellow wrestler Michelle McCool in 2010. While it's yet to be determined if they have the same type of bond, both Cash and Calaway married women inside of their business.

They simply knew nothing else.

Johnny Cash and The Undertaker are synonymous with greatness. They are perhaps the most successful people to ever start a career in their given industry.

They are the men in black.
