One of the saddest and greatest blues songs is So Many Roads.
I nearly wore out the John Hammond LP by that title. At age 18 I wondered what a future love and loss would be like.
But I was later moved by the genuine emotion in the live Joe Bonamassa version on Live From The Royal Albert Hall.
The narrator tried to distance himself by blaming the railroad engineer and brakeman who moved the train in the bleak, lonely night as the woman he loves is leaving him along in his house near the tracks. Helplessness and lost love. A magnificent song and version.
