Pink Floyd

Fairly girls were very much in love
But he doesn't mind
Pickin' up his sister
Makes his way to the see-saw land
All the way she smiled
She goes up while he goes down
Sits on a snake in the river
Laughter in his sleeves
Sister's throwing stones
Hoping for a hit
He doesn't know, so there
She goes up while he goes down
Another time, another day
Her brother's plain to me
Another time, another day day day
