Thanks Durdlin for informing me of the technical term for a misheard lyric or line in a poem: Mondegreen! What a fabulous word! I knew there was some fancy name for my bloopers, so thanks for letting me know!
Now I can happily sing my own lyrics to songs and know that I’m not the only one out there… until this guy falls down on me… (the sky! the sky!!)
For those interested in trivia, the term originates from the ballad of Bonnie Earl O’Murray, which contains the stanza..
Ye Highlands, and ye Lawlands
Oh where have you been?
They have slain the Earl of Murray,
And layd him on the green.
Obviously, the last line can be (and has been) misheard as “..and Lady Mondegreen”, thus the term was coined.
