Olivia: In the winter, springtime, and fall ...
In the summertime, I call you a friend for all seasons.
A friend, so many reasons why I like to be with you.
Just like nature, we change, too.
(Here, I think David sings something, then repeats what Olivia sang)
David and Olivia: Winter, spring, summer, fall.
I wanna spend `em all with you.
Olivia: My friend!
David and Olivia: Winter, spring, summer, fall.
I wanna spend `em all with you.
Olivia: My friend!
David and Olivia: Winter, spring, summer, fall.
I wanna spend `em all with you.
Olivia: My friend!
David and Olivia: Winter, spring, summer, fall.
I wanna spend `em all with you.
Olivia: Winter is cold, the ice and the snow.
David: Springtime is warm; we watch the flowers grow.
Olivia: And the hot sun of summer makes us throw away our cares.
David: Autumn leaves ... (maybe something about frosty air?)
