This thread reminded me. I was clearing up in the attic some time back, and I found my copy of a BBC Broadcast to Schools booklet "Singing Together", dating on 1947, passed out at school by the nuns, and it's on the shelf with my other songbooks.

Lots of good songs in it, including the same version of the sea shanty Whip Jamboree that we've got in the Digital Tradition, with the rousing chorus:

Whip jamboree, whip jamboree,
Oh you long-tailed black man, poke it up behind me,
Whip jamboree, whip jamboree,
Oh Jenny get your oat cake done.
