The teenage Susie version I knew didn't involve knickers - it was 'ooh aah, I lost my bra, I left it in my boyfriend's car' (presumably kids only sang this in areas with non-rhotic accents?)
Then there was 'I had a magic fever, I had it very bad, bad, bad, they wrapped me in a blanket and put me in a van, van, van' then a bit I can't remember, then 'Here comes Doctor Alistair, sliding down the banister, Are you better? are you worse? Oh God blimey, here comes Nurse'
Kids used to walk around the playground with arms linked calling for anyone who wanted to join up for playing a particular game. If it was a popular one there would be a huge line of kids at the end, all with linked arms.
For French elastics we used to say 'England, Ireland, Scotland, Wales, in, out, twist and shout'
