O by the by

O by the by
Has anybody seen
Little you-I
Who stood on a green
Hill and threw
His wish at blue

With swoop and a dart
Out flew his wish
(It dived like a fish
But it climbed like a dream)
Throbbing like a heart
Singing like a flame

Blue took it my
Far beyond far
And high beyond high
Bluer took it your
But bluest took it our
Away beyond where

What a wonderful thing
Is the end of a string
(Murmurs little you-I
As the hill becomes nil)
And will somebody tell
Me why people let go
