Singing in the Bathroom

I have always loved singing,
from the waltz in Tennessee
to the reindeer I can see
by it's nose shining bright on
Christmas Eve.

I tried to sing like Elvis
in the bathroom at school.
From within my soul
I belted,
"Don't be Cruel"

Then came an interruption
a messenger at the school
My songs distracted students
Very much against the rules.
