At Last

At last, my love has come along
My lonely days are over
And life is like a song

At last, the skies above are blue
My heart was wrapped up in clover
The night I looked at you

I found a dream, that I could speak to
A dream that I can call my own
I found a thrill to rest my cheek to
A thrill that I have never known

You smile, oh & then the spell was cast
And here we are in heaven
For you are mine—at last
