Excellent idea for a thread, Ron - and an excellent thread too, jolly entertaining to boot.

At the Wrecks & Rescues show on Thursday night, having been appointed to understudy for my dear darling wife on account of her having lost her voice, I spent much of the day learning her song until I was word perfect. In the performance, however, I took the precaution of having the words nearby. All went swimmingly until the penultimate line, when I glanced at the crib-sheet and got the whole thing in a muddle as a consequence. Thus did can't keep the deep beneath my feet, become can't keep my feet beneath the deep.

So there's my excuse - the song went wrong because I used a crib sheet.

There are folk clubs in a certain city in the North-East of the UK (famous for its many bridges, proprietary brand of fine bottled opaque ale, university degree course in something called Folk Music and a quirky monthly adult-orientated comic which continues to be a national institution despite the fact that it isn't as funny as it used to be) where the use of crib sheets is strictly forbidden. Consequently, the songs usually go right.
