This song is Portuguese
and it says:

“There is joy, there is sorrow
And sometimes they walk
Hand in hand
As you and I
And there is no reason not
To laugh at the sorrow
Or cry from the joy
Because, like us,
They are invited
So let us thank them
For walking with us
On this path we call life
And dance with them
For who knows
What is waiting
For us at the end,
If there is one? ”
