Oh! "When I Grow Too Old To Dream"!! What a *wonderful* old song!
(To me, this is a funeral song, though:)

WHEN I GROW TOO OLD TO DREAM
Words, Oscar Hammerstein II; music, Sigmund Romberg; ©1934.
As recorded by Nelson Eddy, 1935.

VERSE: We have been gay,
Going our way.
Life has been beautiful; we have been young.
After you've gone,
Life will go on
Like an old song we have sung.

CHORUS: When I grow too old to dream, I'll have you to remember.
When I grow too old to dream, your love will live in my heart.
So kiss me, my sweet, and so let us part,
And when I grow too old to dream, that kiss will live in my heart.
