Oh!, for goodness sake...I can't leave this alone! Conventional (sic) dictionaries might not have picked up on the meaning of 'mondegreen' but yourDictionary.com certainly has, viz....

A series of words that result from the mishearing or misinterpretation of a statement or song lyric. For example, I led the pigeons to the flag for I pledge allegiance to the flag.

------------------------------------------------------------------------
[After (Lady) Mondegreen, a misinterpretation of the line (hae laid) him on the green, from the song "The Bonny Earl of Murray".]

A case of Mudcatters in the lexicography department here methinks.
