Ah! - the delights of The Gut. A bottle of Cisk was known as a Bluey the other beer being something like "Hopleaf" and known as a Hoppy. A mate once asked me to bring some Marsovin back from a Luqa detachment for him. The Customs Oficer at Lyneham asked me if it was for my own consumption and not to be caught out I said "Of course!" He replied that it should be marked "For external use only" He was absoutely right - which is why we called it 'Screech" and only drank it on Tuesdays and Wednesdays, mixed 50-50 with lemonade.
