From Wikipedia :- 

Tavistock is a market town within West Devon, England on the River Tavy, from which its name derives, and has a population of 11,018. It traces its history back at least to AD 961, when Tavistock Abbey, whose ruins lie in the centre of the town, was founded. Its most famous son is Sir Francis Drake.

 In 1105 a Royal Charter was granted by Henry I to the monks of Tavistock to run a weekly "Pannier Market" (so called after the baskets used to carry goods) on a Friday, which still takes place today. In 1116 a three-day fair was also granted to mark the feast of Saint Rumon, another tradition that is still maintained in the shape of the annual "Goosey" fair on the 2nd Wednesday in October.

MP3 Here

listen to it on your iPod/MP3 player as you do the cache. Alternatively, transcribe to your cache notes and do the cache 'low-tech'.

This MP3 is quite short - around three minutes, and only covers a couple of hundred yards on the ground. It is meant to 'prove the concept' rather than to be a serious challenge - but the cache is there.

If anyone else wants to place a podcache and is looking for somewhere to host the MP3 file - email me and I can arrange hosting it on the OC UK site.
