Love The One You're With lyrics

Just a song before I go,
To whom it may concern.
Travelling twice the speed of sound
It's easy to get burned.
When the shows were over
We had to get back home,
And when we opened up the door
I had to be alone.
She helped me with my suitcase,
She stands before my eyes
Driving me to the airport,
And to the friendly skies.
Going through security
I held her for so long.
She finally looked at me in love,
And she was gone.
Just a song before I go,
A lesson to be learned.
Travelling twice the speed of sound
It's easy to get burned.
