Thanks for the ideas.
I hadn't though of YouTube, that's a not a bad idea as it would whet her appetite for that particular website whilst simultaneously avoiding the drivel that she normally uses it to watch.
Lessons would be a possible next step, I was just going to start with a book to see if there is any interest there at all (the guitar was free) first. I suppose I should probably add a sodding One Direction songbook as well!
Where did you find that video of me sometime in the near future?
