To save you asking

caller sings
"First couple promenade the ring
All the way till you get back home again
Coming round the mountain, coming round the mountain
Coming round the mountain when she comes
Do ce do your partner one and all*
Swing them round and round, don't let them fall**
Promenade the mountain, coming round the mountain
Coming round the mountain when she comes"

Everyone joins in the "coming round..." bits

* for a slower group could leave out the docedo and sing
"Swing with your partner one and all" etc
**Modified to be gender free - which old square dance calls certainly weren't.
