This site is worth a visit.
Personally composed tunes by the one and only John Bobson (who??), an obvious talent but looks as though he's taking a rest right now (or else he's been taken somewhere, more likely!). Still, around a 100 songs to listen to/download and keep you amused - like 'a guide to cleaning the kitchen floor', olly the fish' (check the accompanying video in the guestbook section), 'syrup on my finger' and many more.
Mentioned this on 'things to do at work' thread but got drowned in all that talk about gaming strategy - shame really. Try it out and enjoy...
