Can you tell me why

it seems so hard to carry on

When you hear a voice

from long ago, so bittersweet

Even though I try, I can not

read between the lines

You know I tried,

Oh, yes, I tried, what´s wrong

Too late to turn back time

To look over my shoulder

Maybe one day I´ll return again

Remember Yesterday

and think about tomorrow

But you have to live today

Oh, lonely yesterday

don´t leave me with the sorrow

Cause I have to live today

Every morning I awake

to see the newborn day

To carry on the flame

until the end of time

Too late to turn back time

To look over my shoulder

Maybe one day I´ll return again

Remember Yesterday

and think about tomorrow

But you have to live today

Oh, lonely yesterday

don´t leave me with the sorrow

Cause I have to live today

Oh, oh, oh, don´t you step aside

and pretend about the future

Oh, oh, oh, never live a lie

don´t you know tomorrow never comes

Remember Yesterday

and think about tomorrow

But you have to live today

Oh, lonely yesterday

don´t leave me with the sorrow

Cause I have to live today

Oh, oh, oh, don´t you step aside

and pretend about the future

Oh, oh, oh, never live a lie

don´t you know tomorrow never comes
