Oh Dang piano

Once I saw a piano
Never knew how to play
There were black and white keys
That’s all I knew for now
Oh dang piano

Then I thought some more
When came zeroes and ones along
Never learnt the code to try and sing again
Oh dang piano

Would it work, I asked,
Couldn’t be bothered, if did not
Thought about the sun now and then
It said, surely it would
Oh dang piano
