Signals from afar

I'm commuting later today, but not to go to work. I shall be attending a theatre workshop, courtesy of U3A. However today's travel news is about Mrs. Commuter's brother and sister-in-law who are on their way to visit us from deepest Yorkshire. Alas, an early morning phone call brought the tragic news that they may be 2 hours late due to, wait for it, stop shuffling at the back, it's your own time you're wasting, I can wait here all day if necessary, right, thank you, so, where was I, ah yes, they will be delayed due to signal failure at (or possibly near) Bedford.  I'm not sure if that's a more glamorous excuse than, say, points failure at Arnos Grove or geese on the line near Upney but anyway there it is. They defied me to put it in this blog. I have risen to the challenge and delivered. And remember you heard it here first, not on Twister or whatever it's called.
