Today, September 23, would have been John Coltrane's 81st birthday. You can hear and see him play "A Love Supreme" and many of his other compositions here. Click your way around for other Coltrane-related material.
I'm not 100 % sure that the Church of St. John Coltrane (African Orthodox) is up and running again, as a few years ago they were facing eviction and then they vanished from view, but they have a very nice website now and this may be a sign that they are indeed alive and well. There are no dates (years, that is) on the website so I'm not sure. Janinsanfran, do you know? There are worship hours listed.
