I think they must have tweaked my voice somehow--I don't usually sound that good when recorded! CR sounded great as usual--he's an old radio hand. Sorry they missed all the naughty bits in "Maid of Australia"--I thought it was very funny that they picked that one. And that was yrlancslad on "Billy Riley."
As for the pontifical Mr. Green--I have sung chanteys while crewing on both squareriggers and schooners, as well as while rowing. The tempo is often either faster OR slower than when the same song is sung for fun, depending on the job. And the song.
