Perhaps you know one of my longtime friends and colleagues, Peter Mapp, 
who does extensive consulting on acoustics and sound systems in the UK. 
Or another, John Woodgate, who is a legend in the world of audio 
Standards. The three of us have served together for decades on the AES 
Standards Committee, and John and I have visited each others homes. John 
took us to a mine where he and his family had survived the Blitz, and a 
place in the woods where parts of the government sheltered.
