More ABBA Gold is a series of twenty puzzles, plus a bonus, inspired by the song titles on ABBA's platinum-selling album, "More ABBA Gold: More ABBA Hits". The caches form a circuit of roughly four miles, mostly on pleasant footpaths southeast of Ash - there are a couple of stretches on country lanes, so please be careful. And be prepared for very wet and muddy conditions!
See More ABBA Gold (the bonus puzzle cache) for an overview of the series.
More ABBA Gold #18: Under Attack
This picture puzzle contains five sets of three clues, with each set having something in common. They lead to a famous performance delivered under duress.
This was one of three memorable performances from around the same time. Taking them in chronological order, use the days and months of the three dates (e.g. A/B/YYYY) to assign values for A to F. (The checksum of the six values is 52.)
