One of my favourite artists is Willie Nelson and for me a big aspect of that is how he sings a song. Willie is known for not singing on the beat. An example of this is a quote from Waylon Jennings:
Typically, Willie is so off the beat when he starts off that Waylon thinks there will be no way for Willie to snap back into the groove. But, he “always comes out of it,” Waylon says. What is it about Willie Nelson’s singing? | genemyers.com (wordpress.com)
So worrying about the “exact” phrasing isn’t the biggest thing we need worry about, Let’s just make it sound good.
Cheers
