It's better to avoid English school holidays as that makes transport much more crowded and difficult. September would be better (early in the month would also let people doing long trips from overseas combine it with a visit to Whitby FF and/or the Edinburgh Festival).

Chorus:
The midgies, the midgies, I'm no gonna kid yiz,
The midgies is really the limit,
With teeth like piranhas they drive you bananas,
If you let them get under your semmit.

The Lord put the Garden of Eden on Earth,
And it's north of the Tweed we believe.
Aye, Scotland's the place
And the whole human race started off with McAdam and Eve.
In 6 days or under, God finished this wonder
Except for the Forth and Tay bridges
Then always a bloke for a practical joke
He made Scotland the home of the midges.

Chorus

Back in 1314, the proud Edward was keen
To take Scotland into his care,
But he made a U-turn when he reached Bannockburn
Just a few weeks before Glasgow Fair.
Oh the midges let loose by King Robert the Bruce
Straight into the English got tore
So they ran off in tears and for 600 years
They've been blocking the A74

Chorus

Now never forget, when the sun's going to set
And the midges arise on Loch Eck
Like the vampires you see played by Christopher Lee
They will give you a pain in the neck.
You can smack them and whack them
In vain you'll attack them,
For they know every move that you make.
If ye manage to kill yin another half million are ready to come to the wake.
