Maid Queen Vs. May Queen

A couple have people have written the same basic message:

Just to let you know the correct lyric [in Stairway to Heaven] is ‘just a spring clean for the maid queen’ not may queen.

Actually folks, it is may queen, but if you looked up the lyrics before emailing me, you’d already know that. What is a maid queen anyway? I bet if I had one my house would be spotless.
