From the recording Touch the Sky
Picking Buttercups is by Kathy Reid-Naiman from her album https://kathyreidnaiman.com/album/874595/reaching-for-the-stars
Lucy of the Tall Grass is a traditional American tune which I couldn't help matching with Picking Buttercups just because of the title.
Lyrics
Lucy’s in the tall grass picking buttercups,
she picks one, she picks two,
and then she stands up
the grass is so tall, and Lucy’s so small
when Lucy’s picking buttercups we can’t see her at all
jump up Lucy, show us where you are
jump up Lucy, show us where you are
Thomas is in the tall grass picking buttercups,
he picks one, he picks two,
and then he stands up
the grass is so tall, and Thomas is so small
when Thomas is picking buttercups we can’t see him at all
jump up Thomas, show us where you are
jump up Thomas, show us where you are
