That's the trouble with being an experimental liturgical unit. You never learn from the past.
I'm sure at least one of the Early Fathers must at some time have written on the dangers of marking out a labyrinth using tea lights. And, if they didn't, I must have. If Beaker liturgical history has taught us one thing, it is that you shouldn't mark out labyrinths using tea lights.
And the other thing it should have taught us - if you do mark out a labyrinth in tea lights, as part of a "Spirit of the 70s" act of worship, don't get so immersed in the recreation of that most holy of eras by walking around the labyrinth in nylon flared trousers.
Hnaef is OK, you'll be pleased to hear. Swift action included wrapping his legs in an afghan rug and beating out the flames. Daphne, in particular, took very swift action, to judge by the vigour with which she was beating them out - long after everybody else had retired to the White Horse, actually.
Hnaef reports this morning that he has no lasting damage, and no hair left on his legs. Says he's amazed by the feeling of confidence that has given him.
