The Blues and religion are always in a contrasting relationship; while many bluesmen associate the music with the devil, god's abandonment due to slavery, hard times, poverty and other negative situations, others believe the music was inspired by minstrels and the gospel, and many sang in churches (such as BB King).
In Junior Wells song 'I Could Have Had Religion' he shows his willingness to turn to religion, but his woman's dirty ways won't let him. In an also unusual first, he talks about the heart attack of Howlin' Wolf, the death of Magic Sam, and Muddy Waters' car accident. It's a very heartfelt tune, with real deep blues.
This song is off the album 'South Side Blues Jam' which was released in 1970, and features blues piano legend Otis Spann (he would pass away the same year), and blues guitar great Buddy Guy on guitar.
