Rotten Little Song lyrics

Sing a la la de de and a la la de do
I just made up this rotten little song for me and you
[ Lyrics from: http://www.lyricsmode.com/lyrics/d/donna_fargo/rotten_little_song.html ]
Today I wrote a rotten melody and the words are just as bad as you can see
But if you want to sing along with this rotten little song
You're as welcome as the flowers in the spring
Just sing a la la for you and a de de for me
And you put 'em both together get a la la de
Sing a la la de de and add a little do
And we'll both sing this rotten little song for me and you

All in all it has been a rotten day and I wouldn't have it any other way
And I won't try to analyze all the if's and but's and why's
Cause I know that it will soon go away
Just sing a la la for you...
Sing a la la for you...
Sing a la la for you...
Sing a la la for you...
