Number 2 - these are in no order.

Singing Together - Summer 1972

As I was going along the road, to see the flowers a-springing - Irish folk song
REap the flax - Swedish folk dance
The Gypsies - Gaelic folk song
Loudly proclaim - Welsh traditional song
Taffta Hindi - Arabian folk song
No other moon - Brazilian folk song
Water come a me eye - Jamaican folk song
Fire down below - English sea shanty

Much more folky - but what is the difference between folk and traditional?
Fire down below reminds me of the first Jennings book, where the boys singing this song reminds the Head to have a drill, with, as they say, hilarious consequences.
