Ivy - Worry About You Lyrics
Bye bye baby.
Don't be long.
I'll worry about you while you're gone.
Bye bye baby.
Don't be long.
I'll worry about you while you're gone.

I'll think of you in my dreams.
You'll never know just what you mean to me.....
....to me.

Hmmm, ba, ba-da...
Hmmm, ba, ba, ba-da......

Bye bye baby.
Don't be long.
I'll worry about you while you're gone.
Bye bye baby.
Don't be long.
I'll worry about you while you're gone.
