In San Francisco

Then one day he met a monkey sitting in the rain
The chimp who somehow had lost a leg
Would soon make Billy change
The vision that the monkey made when Billy touched his paw
Was not too different from the ones he all too often saw
A little girl with golden hair
Who also had one leg
Was sitting by a bowl
The cripples sometimes used to beg

Then another vision came as Billy sat and stared
He realized the monkey and the girl were once a pair
With their two crooked legs the cripples made each other strong
But what really blasted Billy was that young girl's song

Isolated in his mind his world had been complete
Until that simple song released his undiscovered need
With that wistful melody repeating in his brain
Billy hesitated looking out into the rain
For despite the things he had seen a mystery remained
Until the purpose of those other people was explained

But in the ape and chimp he saw a perfect usefulness
So Billy vowed to reunite them in the present tense
