COME AND JOIN US
The Corries

CHORUS: Come and join us. Come and join us. We are the chosen few.
Come and join us. Come and join us at a Scottish barbecue.

1. Now, when the charcoal's burnin' fiercely, and the smoke gets in your eyes,
The steaks all taste like fried toothpaste, and your mouth is full of flies,
You know you've been accepted. You've joined the chosen few,
When you have been invited to a green-belt barbecue.

2. Now, when the summer sun is burnin' in Scotland's happy land,
Round countless fires in strange attires, on many solemn bands
Of unhappy Scotsmen watching their lunch go up in flames,
By the smoke and the smell, you can plainly tell it's barbie time again.

3. Now, the English love their roast beef, the French eat snails and frogs,
The Greeks go crackers over their moussakas, and the Chinese love hot dogs.
A Welshman loves to have a leek, the Irish eat their stew,
But you just can't beat that half-cooked meat at a Scottish barbecue.

4. Now, there's flies stuck in the butter, the bread has gone brick-hard,
The kids are fightin', and the midges are bitin'. Who forgot the Aeroguard?
There's cinders in your whiskey, and the beer is running out,
And what you saw in Mum's coleslaw you just don't think about.

5. And then when the barbie's over, your homeward way you wend.
With a queasy tummy on the family dunny many lonely hours you spend.
You might find yourself reflecting as many others do:
"Come rain or shine, that's the bloody last time I'm goin' to a barbecue."
