I recently had the privilege to travel to the legendary Montreux Jazz Festival (4-19 July) in Switzerland. &ldquoWe all came out to Montreux, on the Lake Geneva shoreline&rdquo this line from the classic rock number &lsquoSmoke on the Water&rsquo by Deep Purple was the first thing that went through my mind. As we know, the song was about the much-publicised fire that broke out during a performance one night in 1971.
