Lyrics:

Bum buttery, flit fluttery
Dum diddly-ooh
Bum Buttery, bluebird
Is singing a tune
Daffy-down-dillies awaken
And prune
Bursting in bloom
All the flowers a**ume
It's a loverly, loverly spring
Chit-chattery chipmunks
All singing along
Humming their
Join-in-a-spring-along song
Spring is the springiest time
For a song
It's a loverly, loverly spring
In the forest we play
With the rabbits all day
We visit the birds and fishes
There's nary a care when there's spring in the air
The feeling is just too delicious
Bum buttercups all in a row
Trilling and frilling and stealing the show
May is the merriest month that I know
It's a loverly, loverly, la la, loverly
La la la loverly spring
This is taken from the end credits, one day when I was bored
