I don't know the first thing about how to work this system but I just wanted to say that Charley Noble's instincts are excellent. The second line as posted is indeed wrong-- it's actually "They had run out of plankton because I had eaten it" I was the one who led the rendition in 1998 at the FSGW Getaway. The author of the song is an Englishman, Sid Meats. I have some other info but have to leave right now for a choral rehearsal
