Hummingbirds hum, why do they hum, little girls wearing
Pigtails in the morning, in the morning
La da da, da da da da

Verse 2:
Merry-go-rounds are going around in and all over
The town in the morning, in the morning
La da da, da da da da

Verse 3:
Summertime's here and look over there, flowers every-
Where in the morning, in the morning
La da da, da da da da
