Lyrics:

Sincerely yours, I sign my heart
Sincerely yours, while we're apart

A friend should whisper things
Let rumors fly
Believe my heart
For darling hearts never lie

Sincerely yours, my love I send
Sincerely yours, until the end
And should you feel as I do
Drop me this line
Sincerely yours, you're mine

Sincerely yours honey, I sign my heart

Sincerely yours, while we're apart

A friend should whisper things
Just let the rumors fly
Believe my heart like you've always done
Remember, hearts never lie

Sincerely yours, my love I send
Sincerely yours, until the end
And should you feel as I do
Drop me this line
Sincerely yours, you're mine
