Thames Valley Morris is a men's Morris side which dances round the South West of London and out into Surrey.
Plus, if you've time to download GIF's:
Sides in the same sort of area include East Surrey, Greensleeves, Spring Grove, Datchet, Yateley, Jackstraws and Hammersmith.
Not all of Thames Valley spend all their time dancing (or playing for) the Morris, Phil plays a little Cajun (ZigaZag) and Jan maintains the Andy Cutting and Karen Tweed pages.
