"Little Letter M" fanspoof: not a bad idea!

After someone brought up the "Mumford and Sons" idea (in a thread about Season 41), I took a look at the original lyrics for "Little Lion Man" and started knocking them around in my head. Even replacing the swearword in the chorus is easier than it looked at first; "messed up" or "mixed up" would be especially good substitutes in a song about the letter M. Picture the Amazing Mumford on a Criss Angel-style magician's stage, with some younger assistants who resemble their father--

"What starts 'myself' and 'man'?
The answer's mighty close to my heart.
Meet little letter M--
it's not as big as it is at the start.
Write it out and read it out,
so many M-words you can find--
Reading's more fun, not many problems
When you make up your own mind."
