we played elastics too in the 1980s in Surrey Uk

the elastic would start at ankle -ees, then knees-ees then thighs-ees etc.

The rhymes i remember were: "England Ireland Scotland Wales, inside outside inside on" and also "Jingle jangle centre spangle jingle jangle on"

Also the way in which you jumped would change depending on the level you were at. It would be jumping but also 'shuffle-eez' which is kind of like jogging on the spot - does anyone recall any other variations / rhymes?
