So the kids and I were just sat around listening to The Beatles (as you do when trying to entertain a 3 year old and a 1 year old). After a while I decide we've had enough and switch it off. 'But we were only up to number 22' says Digby. Baring in mind that the screensaver came on after about track 3 I ask 'How do you know which number it was?' but he doesn't reply. I tap the mouse to bring iTunes back up and low and behold he is absolutely spot on, it is number 22.

I ask him again and he looks up at me, thinks for a second and says 'Because that's the one when JoJo gets back'!

I ask him random track names and he tells me the track numbers. He gets every one of them right!
