Shine a light : 2 August showcases

Joe anounced 2  Showcases in august of the shine a light Tour. I guess we can interpret them as try-outs before the grand tour begins.

I have no view on ticketsale yet ! Neither can I find any other info on these events.
EDIT : Tickets on sale through the Shine a light website. 

1st on in Edinburgh, Scotland on August 15. I assume it is part of Edingburgh's Summerfestival.

2nd one in London,UK in St. Pancras Old Church on August 17. Looks like an interesting place to witness a concert.

Unless there are more St. Pancras old Churches in London, it is one of the  "oldest sites of Christian worship in England."
