Casablanca1942

Ilsa:
Play it once, Sam, for old times' sake.

Sam:
I don't know what you mean, Miss Ilsa.

Ilsa:
[whispered] Play it, Sam. Play As Time Goes By.

Sam:
Why, I can't remember it, Miss Ilsa. I'm a little rusty on it.

Ilsa:
I'll hum it for you. [Ilsa hums two bars. Sam starts to play] Sing it, Sam.

Sam: [singing] You must remember this A kiss is just a kiss A sigh is just a sigh The fundamental things apply As time goes by. And when two lovers woo They still say, 'I love you' On that you can rely No matter what the future brings As Time Goes By.

Lyrics and Music by Herman Hupfeld (1931).
