Brock Lesnar were to perform a sequel to the  song "Convoy" on Raw, it would certainly be a unique and unexpected moment.
The song, originally performed by C.W. McCall, tells the story of a convoy of truckers driving across the country and facing various challenges along the way.


To set the scene, Brock Lesnar could come out to the ring in a trucker hat and a denim jacket, carrying a guitar. 
He could start playing the opening riff of the song and singing the first verse in his high pitch voice. 
As the song progresses, he could act out the various parts of the story, using props like a CB radio or a map.

"Round the world with Brock Lesnar's fists,
You better watch out, you don't want to miss,
The Beast Incarnate is on a tear,
No one can stop him, he's beyond compare."

Brock could encourage the audience to sing along with the chorus and even invite some fans from the audience to come up on stage and join in.
