You sticklers for grammar and diction should stay away from blues songs and sea shanties, then. You'll soon run out of red ink.I am having difficulty understanding why it is wrong to say "I wish I was". I wish I was a Teddy Bear. I wish I was in Kerrickfergus. I wish I was in possession of my Fowler's at this moment.
I understand that the new OED has relaxed the rules of grammar and usage, no doubt to be in keeping with Cool Brittania and young princes in baseball caps. I must get a copy.
