Here's a very simple song written back in 67 by Paul McCartney in the heat of the moment in the studio in response to others in that studio, the song is titled "Hello, Goodbye". It was released in the US on the 'Magical Mystery Tour' Album and later in the UK on the Blue Album.
Here are the lyrics, augmented with my notes (in bold italics) regarding their relevance today.
You say yes, I say no.
You say stop and I say go go go, oh no.
You say goodbye and I say hello
Hello hello
I don't know why you say goodbye, I say hello
Hello hello
I don't know why you say goodbye, I say hello
the general inability of republicans and democrats to communicate productively with each other
I say high, you say low
You say why and I say I don't know, oh no
We disagree yet again for no real reason
You say goodbye and I say hello
(Hello Goodbye Hello Goodbye) hello hello
(Hello Goodbye) I don't know why you say goodbye, I say hello
(Hello Goodbye Hello Goodbye) hello hello
(Hello Goodbye) I don't know why you say goodbye
(Hello Goodbye) I say hello
Why why why why why why do you say goodbye goodbye, oh no?
Sandy Hook
You say goodbye and I say hello
Hello hello
I don't know why you say goodbye, I say hello
Hello hello
I don't know why you say goodbye, I say hello
You say yes (I say "yes") I say no (but I may mean no.)
Rape, Jerry Sandusky, Wide stances
You say stop (I can stay) and I say go go go (till it's time to go ), oh no no
Global Warming
You say goodbye and I say hello
Hello hello
I don't know why you say goodbye, I say hello
Hello hello
I don't know why you say goodbye, I say hello
Hello hello
I don't know why you say goodbye, I say hello hello
Hellooooo
Seems we are unable to communicate
Hela hey helloa
Hela hey helloa Cha Cha Cha
Hela hey helloa Whooo
Hela hey helloa Hela
Hela hey helloa Cha Cha Cha
Hela hey helloa Whooo
Hela hey helloa Cha Cha
Hela hey helloa
make noise in hopes of communication
Hope you enjoy the song:
