Lyrics:

DORIS: Powder your face with sunshine
BUDDY: (Spoken) It always is shiny, Doris
DORIS: Put on a great big smile
BUDDY: (Spoken) You mean like this?
DORIS: Yeah, make up your eyes with laughter
Folks will be laughing with you in a little while

Doris:
Whistle a tune of gladness
Gloom never was in style
The future's brighter
When hearts are lighter
Smile, smile, smile

Buddy:
Powder your face with sunshine
Put on a great big smile
Make up your eyes with laughter
Folks will be laughing with you in a little while

Just whistle a tune of gladness
Gloom never was in style
The future's brighter
When hearts are lighter
Smile, smile, smile

Both:
Whistle a tune of gladness
Gloom never was in style
DORIS: The future's brighter
BUDDY: When hearts are lighter
BOTH: Smile, smile, smile
