When you find your sweetheart in the arms of a friend
That's when your heartaches begin
When dreams of a lifetime must come to an end
That's when your heartaches begin

Love is a thing you never can share
When you bring a friend into your love affair
That's the end of your sweetheart
That's the end of your friend
That's when your heartaches begin

[Spoken]
When you find your sweetheart
In the arms of your best friend, brother
That's when all your heartaches begin
When dreams of a lifetime
Must all come to an end
That's when your heartaches begin
You see ,love is a thing
That you never can share
And when you bring a friend
Into your love affair
That's the end
That's the end of your sweetheart
Jack, I'm tellin' ya, that's the end of your friend
[Sung]
That's when your heartaches begin
