I know this is not the same song (and it was written by Dave Webber), but it is a firm favourite amongst folkies in Oz and my friends and I in the Top End would always carouse with it around May 1st.   In the Top End it helped herald in "The Dry" season, whereas in SE Qld where I now live, this year May 1st (yesterday!) brought us an intense chill, warning of The Winter to come!

Here is a version of Dave's "May Song" (aka HAIL, THE FIRST OF MAY) by Magpie Lane, with some great pics too :

And a CV19 Mayday has been disruptive for Morris Dancing rituals everywhere (e.g. Dancing Up the Sun, at dawn on Mayday).
Here is a blog reporting the issues, from Qld, ending with a song by the lovely Nicole Murray of Cloudstreet called "Let Winter Begin" :
