Let the time flow, let the love grow,
Let the rain shower, let the rose flower.
Love it seeks, love it finds. Love it conquers, love it binds.

We come to each other from different worlds.
Drawn to each other by the love inside of us.
We give to each other our different worlds.
As long as we can do it, life’s is going to breeze right through it.

Let the time flow, let the love grow,
Let the rain shower, let the rose flower.

Love it seeks, love it finds, love it conquers, love it binds.
Love it seeks, love it finds, love it conquers, love it binds.

The theme went as high as #18 on the Billboard Top 40 Charts in 1979.  Maureen McGovern is a singer who occasionally acts (Towering Inferno and Airplane (She was Sister Angelina). She had a #1 hit with the song The Morning After, which was the love theme from The Poseidon Adventure (yeah, I know, the 70s were really weird . . .).
