I recently posted a video on the many songs in bluegrass that seemingly have strange chords, but can be explained with the Circle of 5ths. In this video, I share numerous bluegrass songs that don't follow the logic of the Circle, but still explain how to find them in any key using the Circle. I call it the Circle of 5ths Debunked!
Mr Sandman and Red Roses for a Blue Lady largely follow the circle of 4ths. Does that count?
Thanks Eddie! Love your material.
