The cache is not at the published coordinates, which are for Tittenhurst Park, a private 72 acre estate. Both John Lennon and Ringo Starr have lived here in the past. Other famous previous residents include Thomas Holloway (who built the Georgian mansion), Yoko Ono and Ringo Starr. Presently, the property is owned by the president of the UAE and ruler of Abu Dhabi. The picture on the album cover of "Hey Jude" was taken at the entrance to the property.
However, in order to find this cache, you need to find the identity of another Berkshire resident, who shall be referred to as person "X", who currently lives a short distance away.
X was born on April Fool's Day, which some may say is not coincidental
To date, X has written two autobiographies
X has an entrepreneurial streak and in their early career set up a detective agency and a kiss-ogram service
The cache is located at N 51 24.ABC W 000 38.DEF, where AC = the age of the Person X on the date of publication of this cache, Person X married a pop singer in 200B and DEF = the number of minutes that Person X's show lasted on 19 July 2010
You are looking for a container about the size of a 35mm cannister, which can be found as a very quick drive by.
