I sing in a choir. Last weekend we sang in a cave.
It was one of the most surreal episodes of my life.
The Jenolan Caves are under the Blue Mountains, about three hours drive
from Sydney. We were going to perform in one of the larger chambers,
the Cathedral Cavern, an intricate gash in the rock with a 54 meter
high ceiling. We descended the 910 narrow stone steps and lay in wait
for the unsuspecting members of the public who had signed up for a
"cave tour and gospel choir" package. When their tour entered the
Cathedral Cavern they found a waiting choir and rows of picnic chairs.
We sang our hearts out, popped round the corner into another cavern
then back for an encore, congratulated each other with high-fives, then joined at the back
of the group for the rest of the cave tour! It was, like I said,
surreal.
Here we are busking outside the entrance to the cave.
Here we are milling about inside the cave waiting for the audience (we were told not to touch anything).
And here we are singing inside the cave!
The tour was brilliant. The guide used just the right level of technical detail in his descriptions. There was none of this "cave origin via sulfuric acid speleogenesis and recognition of microbial mediation of cave processes, blah blah blah..." rather, "There are two types of rocks down here. Waxy rocks and shiny rocks. That's a waxy rock, see how it looks waxy? And that's a shiny rock. See how it shines?" You get the idea. Perfect, especially catering for the attention span of possibly the world's first post-gig-party cave tour. The guide proceeded to point out all the stalactite formations that looked like funny objects. We found other ones that were even funnier.
We were taken to the first cave in the world to get electric light (how do they know that?). First we were shown the cave lit up by green light (ooh!), then blue light (ahh!) then red light (ugh). There was one cave where animals used to fall in and die becuase they couldn't climb out. To illustrate this the subtley lit bones of a wombat were pilled up in the corner. This fascinated us.
At the end of the tour the guide asked for questions. Someone asked why there was a tap in one of the caves. Brilliant question! Millions of years of geological history and we want to know about the tap! Tell us about the tap! The guide replied that with they have to wash the caves. With thousands of visitors passing through each year shedding skin, hair and lint, apparently the caves get a bit fluffy.
