I suspect JudeL got the Tessie O'Shea version from me, because that's the version I've sung at Herga, Maidenhead, and Wycombe (and probably Uxbridge too!. The words that Jim McLean has posted have been published by EMI Music Publishing Ltd(with the music) in the Bumper Book of Music Hall Songs.

In the Tessie O'Shea version, I thinks it's "foiled" the Demon King, not "followed". The fairy was with the good guys.
