It's scooters for grown-ups really, isn't it, and why not? You often see parents riding their child's scooter home from school. And talking of school, the "Push Bike Song" takes me straight back to my fourth year at secondary school (c1971) when we had a form teacher who was old, wise and surprisingly liberal. He allowed us to have a record player in the classroom so we could have music during our breaks, and The Push Bike Song was definitely our favourite at that time. There was a problem at one point when some of the rowdier elements of our class amused themselves by using their geometry compasses as darts, and the back wall of the classroom as a dart-board, damaging the wall cladding and posing the risk of someone being blinded by a compass point. Most teachers would have responded with threats and punishments, but not ours. Knowing that one of the culprits was gifted at art, he got him to design a giant abstract mural to cover the whole wall, and provided the rest with paints and brushes to carry it out, which they did with great enthusiasm. End of problem! He was quite a guy.
