we were nothing but a pint of memory
if it's alright with you
then it's alright with me

i think about you now and then
you know my pace eludes so big with all this space
you don't know why i should miss you now but see
if it's alright with you
then it's alright with me
if it's alright with you
then it's alright with me
yeah~

i can't tell but
you're on my mind
but i won't even try
to make you change your mind
i know i'd better let your go and see
if it's alright with you
then it's alright with me
if it's alright with you
then it's alright with me
if it's alright with you
then it's alright with me
if it's alright with you
then it's alright with me
