I've written quite a few Tolkien parodied songs, and I thought I'd share 'em with ya. This is my favorite:
...Roll Over Oh Tolkien!
Originally "Roll Over Beetoven" by the Beatles
Well gonna watch a movie
Directed by a guy called P.J.
It's a rockin' little story
I went to watch it today
Roll over O Tolkien
I gotta see it again today
.You know my temperature's risin'
And the book fan's blowin' a fuse
My hearts beatin' rhythm
And my soul keeps singing the blues
Roll over O Tolkien
And tell C.S. Lewis the news
.I got permanent nausea
The bookies scream "O save us Eru!"
I think we'll mob the writers
Reading Roger Ebert's review
Roll over O Tolkien
Orli fans marchin' two by two
.Well if you feel that you like it
Well get your LotR and read and love it
Read it over and move on up
To the Silm and read and love it
Read it over
Roll over O Tolkien
A walkin' in two by two , oh
.Well early in the mornin'
I'm a givin' you the warnin'
Say goodbye to light elf shoes
Hey diddle diddle
Say goodbye to Nob's fiddle
So much of the story to lose
Roll over O Tolkien
And tell C.S. Lewis the news
.You know she glows like a glow worm
They went a bit over the top
She got a mortal partner
Will she stay an elf or not?
Long as she's got Asfaloth
Arwen will never stop
Roll over O Tolkien
Roll over O Tolkien
Roll over O Tolkien
Roll over O Tolkien
Roll over O Tolkien
And dig these rhythm and blues
...I've got lots more...
