In the song “Casey Jones,” performed by the Grateful Dead, the rhythm is more upbeat than in it is in the other versions.  The chorus of the song is sung the same way every time it is repeated.  The verse that starts off with “trouble ahead, lady in red” is the first verse in which the singer sings differently.  He slowly lets out the word “lady” which makes the tempo of that verse different than the others. 

The artist sings the song differently again when it comes to the last verse.  He sings the lines “trouble with you is the trouble with me” and “come round the bend, you know it’s the end” in the same tone.  It seems as tough the expression changes towards the end of the song because the artist is getting ready for the song to be over.  The song begins to speed up before it finishes.
