When the tides of all the oceans dry
And the birds on earth cease to fly,
Or when the alps lose all their snow
And stars in Heaven no longer glow,
When northern winds subdue their gusts
And drops of rain turn into dust,
After skies lose their color blue,
Even then...I will still love you.
Tod Denny
