WYSIWYG point out that Duffers could be consumers of that marvellous concoction favoured by Homer (The yellow one, not the Greek). So to get back to music, I'll misquote Homer.

The Duffers Anthem.

Duff beer for me,
Duff beer for you,
You have a Duff,
I will have two!

Duff beer for you,
Duff beer for me,
You have a Duff,
I will have three!

Duff beer we drink,
Duff beer we pour,
You have a Duff,
I will have four!

Duff beer's the drink
That keeps us alive...(continue ad nauseum!)

Cheers! Nigel
