Back in 1963, two old worthies (Dookers) sitting at Tarbert harbour, smoking their pipes and chewing the fat.
The first one says "Here - have you been reading the Courier ? It says that yon Secretary of State For War called John Profumo has been caught having sex with some lassie called Christine Keeler. They say she's a Call Girl"
The second one thinks hard and says "I don't know of any Keilers on Coll. She must be from Tiree !"
