Loads of things mentioned here, with variations. I remember 'chinny' and beard-stroking but no idea exactly what we said.
Our Susie did 'goo, ga, ga ga goo' as a baby. As a schoolgirl she went 'Miss, Miss, I can't do this, I don't know where my pencil is' and as a teenager 'ooh, ah, I've lost my bra, I left it in my boyfriend's car'
French elastics was England, Ireland, Scotland, Wales, in (both legs in) out (both legs out) twist (turn 90° so the elastic was twisted round your legs) and shout (hop out).
Orange peel - we'd dance in a circle singing 'Orange peel, orange peel, here we go again, hey' x2 - on each 'hey' was a kick/jump in the air, on the second one we all had to sit down on the floor and the last one down was dragged into the middle and we danced round them singing 'xxxxx (name of another kid) is your girl/boyfriend, tra la la la la la'
We had the Billy rhyme - it went 'My friend (?cousin) Billy had a ten-foot willy and he showed it to the girl next door/She thought it was a snake and hit it with a rake and now it's only six foot four'
Then there was this - maybe someone can complete?
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
The van was very bumpy (bump up and down), it made me feel quite ill, ill, ill
[line I can't remember here]
Here comes Doctor Alastair, sliding down the banister
'Are you better? (throw your arms out) Are you worse? (cuddle yourself with your arms) Oh God blimey, here comes Nurse!' (said in manner than indicated he was very scared of Nurse)
