First of all, this song is by a British group and they are using idoms Americans are not familiar with. For example I know what a hedgerow is, but I am sure some Americans will not. 'West' is a metaphor for death. Sun rises in the east and sets in the west.
And so on.
Thing is, it is actually VERY English LOL!
No comparison whatsoever to tongues in the Bible.
As for spring clean for the may queen, looked it up and I bet most English people (English from England) know what that refers to. The May Queen is an English tradition, not American, so again, might sound like babble to you but it isn't.
You are looking at the terms from the exoteric perspective. That whole song is about pagan god worship.
In ancient Rome the first day of May fell during the festival of Floralia, named in honor of Flora, the goddess of springtime and flowers. It was a time of singing, dancing, and flower-decked parades, and also to hang flowers on a loved one's door. Roman prostitutes especially enjoyed the festival, for they considered Flora their patron goddess.
The New Funk & Wagnalls Encyclopedia says on page 8294:
“May Day festivals probably stem from the rites practiced in honor of a Roman goddess, Maia, who was worshiped as the source of human and natural fertility.” A conspicuous feature of this celebration has been (and still is, especially among school children) the dancing around the Maypole.
The same encyclopedia states: “This Maypole is believed by most scholars to be a survival of a phallic symbol formerly used in the spring rites for the goddess Maia.”
According to the polemic anti-Catholic pamphlet, The Two Babylons, the origin of the maypole dance began in ancient Babylon during sex worship and fertility rites. The church of St. Andrew Undershaft in the City of London is named after the maypole that was kept under its eaves and set up each spring until 1517 when student riots put an end to the custom. The maypole itself survived until 1547 when a Puritan mob seized and destroyed it as a "pagan idol".
