I think she actually does her version in the key of "D" but this is how I transposed it.
(If you capo the 2nd fret its sorta the same).
From the very first time I rest my eyes on you, boy
My heart said "follow through"
But I know now that I'm way down your line
But the waiting feel is fine
See don't treat me like a puppet on a string
'Cause I know how do my thing
Don't talk to me as if you think I'm dumb
I wanna know when you're gonna come- see
(Chorus)
I don't wanna wait in vain for your love (repeat 3 times)
(Bridge)
'Cause summer is here and I'm still waiting there
Winter is here and I'm still waiting- there
Its been three years since I'm knocking on your door
And I still could knock some more
Oooh boy, oooh boy
Is it crazy, look I wanna know now- for I to knock some more
You see, in life I know there is lots of grief
But your love is my relief
Tears in my eyes burn, tears in my eyes burn
While I'm waiting, while I'm waiting for my turn- to see
(Chorus)
I don't wanna wait in vain for your love (repeat 3 times)
(Repeat Bridge)
I don't wanna
I don't wanna
I don't wanna
I don't wanna
I don't wanna wait in vain (fade out)
