Deckchairs on the Titanic

‘Deckchairs on the Titanic’ is one of those clichés banned by John Rentoul in his Banned List book. So I should be wary about using it in a post, after praising John’s campaign for plain and fresh English.

But I’m prompted by a letter in today’s Guardian from Colin Shone reporting a promotion for Wrexham Lager ‘as served on the Titanic’. Is there an opportunity here for deckchair makers?
