Although the protagonist is named after Al Jolson, he does not sing in a Jolson-styled voice.
Tommy Bond is perhaps better remembered as "Butch" of the Our Gang / Little Rascals film series.
The father owl was first voiced by Bert Lahr, but re placed by Billy Bletcher for the final production.
As this is one of the most requested cartoons on the DataBase, so we thought we'd include the lyrics to the original version of the song (as performed by Al Jolson with Cab Calloway):
I love to sing-a
About the moon-a and the June-a and the spring-a,
I love to sing-a,
About a sky of blue-a, or a tea for two-a,
Anything-a with a swing-a to an "I love you-a,"
I love to, I love to sing!
Give me a song-a
About a son-a gun that went and done her wrong-a.
But keep it clean-a,
With a cottage small-a by a waterfall-a,
Any sob-a that will throb-a to a bluebird's call-a,
I love, I love to sing!
I was born a singin' fool-a,
Lah-de-dah!
Ol' Major Bowes is gonna spot me,
Got through Yale with boula-boula,
Lah-de-dah!
Old microphone's got me!
I love to sing-a,
I love to wake up with the south-a in my mouth-a,
And wave a flag-a,
With a cheer for Uncle Sammy and another for my mammy,
I love to sing!
The swingin'est,
Hot singin'est,
Bell-ringin'est,
Song singin'est
High tootin'est,
Sky tootin'est,
I love to sing!


I Love To Singa
