'I for one am happy that what we sung at primary school in the 1950's was influenced by that movement rather than having justr posh songs aimed at posh kids. (plus Hymns Ancient & Modern ...)'

Me too, jag.
The first song I ever sang in a folk club was the version of Sally Brown I'd learnt at school. Wraggle-taggle Gypsies, Jolly Wagoner, the Keeper and all the rest must have contributed to my early love of folk song.

I also had no qualms at recording the versions sung by farm labourers who had learnt them at school, along with those they had learnt in their communities.

Sharp didn't alter much of The Keeper though we kids had no idea of the real meaning. I sometimes wonder if Sharp did.
