Feist 1234 lyrics

one, two, three, four,
tell me that you love me more.
sleepless, long nights.
sighs, what my youth was for.
oh, teenage hopes
are alive at your door
left you with nothing,
but they want some more
oh, oh, oh,
you're changing your heart.
oh, oh, oh,
you know who you are.
one, two, three, four.
