As a venue, The Union Chapel rises serenely above the sticky floors of its close neighbours The Hope & Anchor and The Garage.  It balances its roles as fully functioning church and celebrated concert hall with ease and, if you’re after a sense of reverence and ceremony, there aren’t many London venues that can match it.  On this balmy May evening, Scott Matthews' disciples gather respectfully along the ridiculously up-at-heel Compton Terrace long before doors open and I have the distinct impression that I am in for one of the more civilised gig-going experiences of my modest career.  I install myself in pew 77 with a Coke (no alcohol allowed in the church itself) and begin to contemplate my manifold sins.
