This day in music history.

March 2, 1968, The members of Pink Floyd are in the recording studio. Syd Barrett told the others that he had a new song to teach them, he said it was called "Do you get it yet" after Syd taught them the song they all tried to play it together and Syd stopped them saying they were playing it all wrong, so he showed them again and once again when they played it back Syd stopped them saying it was all wrong. This continued for a while and every time he played it Syd changed the melody and chord progression. Finally Roger Waters got the joke.
The Effervescing Elephant by Syd Barrett
An Effervescing Elephant with tiny eyes and great big trunk
once whispered to the tiny ear the ear of one inferior
that by next June he'd die,
oh yeah!
because the tiger would roam.
The little one said: "Oh my goodness I must stay at home!
and every time I hear a growl I'll know the tiger's on the prowl
and I'll be really safe, you know the elephant he told me so."
Everyone was nervy,
oh yeah!
and the message was spread to
zebra, mongoose, and the dirty hippopotamus
who wallowed in the mud and chewed his spicy hippo-plankton food
and tended to ignore the word preferring to survey a herd
of stupid water bison,
oh yeah!
And all the jungle took fright, and ran around for all the day and the night
but all in vain, because, you see, the tiger came and said: "Who me?!
You know, I wouldn't hurt not one of you.
I'd much prefer something to chew and you're all to scant."
oh yeah!
He ate the Elephant
