It seems pretty common for rock/country/folk artists to bend grammar to accomodate the lyrics or rhythm of the song. GL is no exception and I was just listening to Slide on Over last night contemplating this line...
"Now we got it rolling, how're we gonna get it stopped?"
Get it stopped?!?!
I imagine an English teacher reading these lyrics and whipping out the red pen to circle this line; perhaps writing in the margins the correct "how are we going to make it stop?" LOL!
However; I don't doubt GL is aware of his use of grammar and concur that sometimes in modern music "proper english" just doesn't sound as good!
