My niece is named, in part, for this song. It's one of the first "pop" songs I remember learning.

From Lyrics World:

TAMMY- from "Tammy and the Bachelor" starring Debbie Reynolds and Leslie Nielson
- words and music by Jay Livingston and Ray Evans
- #1 hit for Debbie Reynolds in 1957- #5 hit for The Ames Brothers in 1957

I hear the cottonwoods whisp'rin' above
Tammy! Tammy! Tammy's in love!
The ole hootie owl hootie-hoo's to the dove
Tammy! Tammy! Tammy's in love!
Does my darling feel what I feel
When he comes near?
My heart beats so joyfully
You'd think that he could hear!
Wish I knew if he knew what I'm dreaming of!
Tammy! Tammy! Tammy's in love!

Whippoorwill, whippoorwill, you and I know
Tammy! Tammy! Can't let him go!
The breeze from the bayou keeps murmuring low
Tammy! Tammy! You love him so!
When the night is warm, soft and warm
I long for his charms!
I'd sing like a violin
If I were in his arms

Wish I knew if he knew what I'm dreaming of!
Tammy, Tammy, Tammy's in love!
