Da Da, La La, etc

This song we sing,
It sounds just so pretentious
No words, just la's
It seems so La de da.

This song we sing,
It seems so high falutin'
Voices so grand
Just see how straight we stand!

With these words
Our song is bent,
It becomes irreverent.
Words like these, can change the song
Maybe that's where we went wrong?

Words are what made this song go oh so wrong.
