The trio began their collaboration with a performance at the ancient Baths of Caracalla in Rome, Italy on 7 July 1990, the eve of the 1990 FIFA World Cup Final. The recording of this debut concert became the best-selling classical album of all time and led to additional performances and live albums. They last performed together at an arena in Columbus, Ohio, USA on 28 September 2003 [Source: Wikipedia]
This regular-sized cache has space for a log, a pen and pencil, and treasures. Yes, it really is a Regular size because it's less than the 20L volume minimum to be a Large.
There is enough space to park on the road verge near GZ, however, beware of the ditch nearby. Please be safe and please don't drive into the ditch. In warm weather and long grass there is the possibility of snakes in the area.
My thanks to cachers Julie&GGs who suggested the Three Tenors be included in the series.
