For longer than I care to remember I have been able to dash off daft rhymes, verse call it what you will.
In the past I have on occasion written them to order, best man's speeches, special birthdays, other events etc. (I remember a particularly poignant one for the funeral of a friends nephew)
Usually they are just standard verse stuff, but I did a couple of parodies of Shakespeare sonnets on the Pete's Sports Bar thread. I've also from time to time played around with alternative song lyrics (one on *Micelfs red ink thread) including a version of Waltzing Matilda for a work colleague who was emigrating and alternative words to Led Zeppelins "Stairway to Heaven" formed part of my work for English GCSE.
I have been able to produce something even if I don't know the person concerned, providing I'm given a bit of back ground and a couple of anecdotes.
So, if any Grans would like something written for whatever reason, I'd be happy to have a bash!
