I'm so glad
I'm so glad
I'm glad, I'm glad, I'm glad
I'm so glad
I'm so glad
I'm glad, I'm glad, I'm glad

Don't know what to do
Don't know what to do
Don't know what I'm gonna do
Another week in
Telephoning
Tired of groaning for you

I'm so glad
I'm so glad
I'm glad, I'm glad, I'm glad
I'm so glad
I'm so glad
I'm glad, I'm glad, I'm glad
