I reckon at the bottom of Gaping Ghyll would be pretty cool - it's a pot-hole in the Yorkshire Pennines, supposedly big enough for St Paul's Cathedral to fit it.

Just one snag - it's about a 3 hour hike up a mountain to get to the hole in the ground which you then drop through, I think about 300-odd feet

The extreme cellos have a Facebook group, I think. We tried (unsuccessfully) to get them for a recording session...
