Thanks to Spotify, I now have access to the whole recording:


HAPPY BIRTHDAY POLKA
As sung by the Sons of the Pioneers on "The Very Best of" (2011)

Happy birthday!

Happy birthday! Happy, happy birthday!
This is your day to have a lot of fun.
We're all waitin' for the celebratin'.
We'll keep goin' until the night is done.
Blow out the candles on the cake and make a wish,
Then we'll serve ev'rybody's fav'rite dish.
Happy birthday! Happy, happy birthday!
It's your party but we have all the fun.

Gather around the piano.
We'll harmonize a few.
"Sweet Adeline"—
"Dear Pal o' Mine"—
We'll sing the whole night through.
If someone thinks we're too noisy,
And knocks upon the door,
Invite them in and then begin,
One voice louder,
One voice louder,
One voice louder than before.

Happy birthday! Happy, happy birthday!
This is your day to have a lot of fun.

Happy birthday!

Happy birthday! Happy, happy birthday!
This is your day to have a lot of fun.
We're all waitin' for the celebratin'.
We'll keep goin' until the night is done.
Blow out the candles on the cake and make a wish,
Then we'll serve ev'rybody's fav'rite dish.
(Happy birthday to you!)
Happy birthday! Happy, happy birthday!
It's your party but we have all the fun
