\begin{my-verse}
Somewhere over the rainbow,\\
Way up high\\
There's a land that I dreamed of\\
Once in a lullaby.
\end{my-verse}
\\[-2em]
\begin{my-verse}
Somewhere over the rainbow,\\
Skies are blue\\
And the dreams that you dare to dream\\
Really do come true.
\end{my-verse}
\\[-2em]
\begin{my-verse}
Some day I'll wish upon a star\\
And wake up where the clouds are far behind me.\\
Where troubles melt like lemon drops\\
Away above the chimney tops\\
That's where you'll find me.
\end{my-verse}
\\[-2em]
\begin{my-verse}
Somewhere over the rainbow,\\
Blue birds fly\\
Birds fly over the rainbow\\
Why, then, oh, why can't I?
\end{my-verse}

\begin{my-verse}
If happy little bluebirds fly\\
Beyond the rainbow\\
Why, oh, why can't I?
