Could it be patch instead of bush? I remember this one:

PAW-PAW PATCH

Where, oh where, oh where is Susie?
Where, oh where, oh where is Susie?
Where, oh where, of where is Susie?
Way down yonder in the paw-paw patch.

Chorus:
Picking up paw-paws; put 'em in a basket.
Picking up paw-paws; put 'em in a basket.
Picking up paw-paws;put 'em in a basket.
Way down yonder in the paw-paw patch.

Come along, boys, and let's go find her.
Come along, boys, and let's go find her.
Come along, boys, and let's go find her.
Way down yonder in the paw-paw patch

Repeat Chorus:

She's a queen of old Hawaii.
She's a queen of old Hawaii.
She's a queen of old Hawaii.
Way down yonder in the paw-paw patch.

Repeat Chorus:

She can teach you how to hulu.
She can teach you how to hulu.
She can teach you how to hulu.
Way down yonder in the paw-paw patch.

Repeat Chorus:

Melody is very close to "Git along home, Cindy" if not the same.
