Lyrics:

To everybodys heart there is a key
A key called love
But isn't it the greatest Mystery
So soft and tough
Memories come, memories go
And when they're gone time will show
Love is like a mystery
Just a game for you and me
Love is like a mystery
Over and over again
Love can be a tragedy
Sad and lonely it can be
Love is like a mystery
Over and over my friend
In every little flying Butterfly
Inside your heart
There lies this secret key for you and I
Right from the start
Memories come, memories go
And when they're gone, time will show
Love is like a mystery
Just a game for you and me
Love is like a mystery
Over and over again
Love can be a tragedy
Sad and lonely it can be
Love is like a mystery
Over and over my friend
