This raises the question as to whether there is (or ever was) a 'standard' Maypole. I always thought that you made your pole to your own concept and danced around it. You should probably bear in mind that the Puritan Stubbs called the Maypole a 'filthy, stinking wickedness', so once you've obeyed all the construction, planning, licensing, health and safety laws, be careful what you dance!
At Maytime in Bluefields, on the Atlantic Coast of Guiana, they dance a wonderfully erotic May dance called 'The Four Old Ladies' (actually 3 ladies and a fourth one dressed as a man). After I'd seen that on a TV film I began to understand what Stubbs was raving about.
