Blue Letter lyrics

(Richard & Michael Curtis)

it was a blue letter she wrote to me
it's silver words she told
"wanna be on the road to paradise,
i wanna lover who don't get old"
do i read the message in your eyes
you wanna love to stay another night
hey baby when your day goes down
i won't be waitin' around for you
for every voice you ever heard,
there's a thousand without a word
red bird...don't say you told me so,
just give me one more song to go
(repeat chorus)
