how about "two balls" and that's what we called it!
where the girls in the main, would fetch two tennis balls into school and play them against the wall.
to the infamous songs of...
"mathew, mark , luke and john,.. next door neighbour pass it on," then one girl would take over the balls and play them against the wall. and then continue... this sounds a bit naff now when you try and explain it, but it was good at the time... from what i can remember!
so many other songs that you could play "two balls" with, but my mind has gone blank.....
anyone else do this at school????
