More on Jazz in church
Lots of discussion on Sing of the Lord's Goodness below.
I don't think the piece is so hard to sing. The rhythm is catchy. It is a little high for your average person.
The catch is: the sound of it and its connotation. Close your eyes and sing the song - are you in church, or some smokey club, working on your 2nd G&T and smoking menthol cigarettes? Are you wearing a stupid hat and sunglasses even though it's 11pm? Do you have a bag of weed under the passenger seat?
If you answered yes to any of those questions, you understand the cultural baggage of jazz and why it's non-liturgical, even anti-liturgical music.
Or it could just be extra-liturgical music. Maybe this town needs a group of Jazz musicians who are dedicated Christians.
Jazz for Jesus.
