very shortly after the "Brexit" referendum in the UK, I rewrote Pat Sky's Separation Blues. His verses stand the test of time better than mine, some of which are already history - but I havent decided if and how to rewrite the EU SEPARATION BLUES   
(tune and verses in brackets adapted from original song by Patrick Sky, Separation Blues)

Will we stay or will we go
to buy and sell via the WTO?
Maybe we can join the EFTA,
stay in the single market but without much say
You know we've got, got the indecision blues.

Farage says "We're British, we do as we please;
You never ever worked", he told the MEPs
That made the Europeans hiss and boo
"You don't like us; hell, we sure don't like you
You can go and get, get the separation blues."

~"It's time," Farage says, "to put Britain first,
Get out from under Europe's thumb.
It's better to leave
than be besieged by the migrant scum"

(they say) "Leave the union, better leave it quick
Leave the Eunion, better leave it quick,
Leave the European Union, leave it quick
If you voted for Brex-it.
It's time to get, get the separation blues."

[See that fly, crawling up the wall (3x)
He don't speak to Mrs Spider at all
Cos you know they've got, got the separation blues]

"We're better off out," said Johnson to Gove
But when Leave won the vote, Mike gave Boris the shove.
We thought they were the best of friends
But Boris hesitated and that was the end
And now they've got, got the separation blues.

~ Which only goes to show, since it all began
The referendum was a power game
Win or lose, whatever you chose
Politicians act the same.

Gove says "Leave the competition,leave it quick
Leave the party race, better leave it quick,
You can leave the party, leave it quick
If you're lukewarm about Brex-it.
It's time to go and the separation blues."

[The last words that poor John the Baptist said (2x)
Last words John the Baptist said, before he went and lost the head was
This gives me. gives me the separation blues]

~In case you need reminding the decision isnt binding
but it's clear its time for change
We need negotiation not recrimination
whether we leave or remain

Labour and Tory are in a terrible fix
Since the vote in favour of Brexit
Jostling for position, every woman and man
They need to get together and sort out a plan
Cos everybody's got, got the separation blues

Should we stay, or should we go?
Don't ask me, cos I really don't know
Got to get our heads together, or before you know
The UKIP will be running the show – and that gives me,
Gives me the EU separation blues.
