This is one of a series of 50 caches to celebrate arguably the most influential decade in the history of popular music, the swinging sixties, so grab a granddad to help you out. The clues relate to artists, records &/or films of the decade and will require Internet searches to work out the final co-ordinates of the cache. What you have to find will be made clear in the narrative, but firstly you will need to work out the name of artist(s), song, album or film titles. As an added bonus for finding one of these SS caches, each cache will contain an additional clue to another SS cache. If you are lucky it may be one you will have yet to find, or not, as the case may be as the caches can be attempted in any order.
