@maculata I never learnt it, but as a teenager I knew a large number of scout/rover types who did. Every party, 18th, 21st, even a couple of weddings, it would come on and every one of them would get up and do it. At the time I felt very left out, but later I realised I’d been lucky.

(I may be deported now I’ve publicly admitted I never learnt it.)
