But I'm confused about the lyrics. Malcolm Douglas and others say the words were written by D K Gavan, 'The Galway Poet', for the English music hall performer Harry Clifton (1824-1872), who popularised the song. Are there other songs with this title, or do all the lyrics posted with this title - I would guess that all the "in the merry month of May/June" songs are the same, but we see various attributions.

This is what I put above for the source of the tune: Tune obtained from sheet music published for Harry Clifton, with words by Gavan. Composer of tune unknown, possibly traditional - is that accurate?

for the tune for this song from the Digital Tradition. I'd say it's more-or-less the same tune - isn't it?
