I was going to suggest to Adolfo that his tape must be the McCalmans, since he mentions that the songs "My Johnny is a Shoemaker" and "Charles in France" are both on his tape. These two songs are performed on the McCalmans' LP "An Audience with the McCalmans", a live LP. But in his message at 19 Apr 04 - 04:43 PM he quotes a verse that isn't sung by the McCamans, so now I am confused! Adolfo, do the songs have close harmony singing, especially the choruses? Is it a live performance, I mean can you hear any applause from an audience? If so, I am sure it must be the McCalmans.

Anyway well done Malcolm Douglas for finding the source. I have used the link you provided to help me transcribe the way the McCalmans sing it (see following message). Apart from shortening it drastically like you said, the only changes they have made are as follows:
Verse 1, line 4: they sing "Hear" where the poem has "Hark"
Verse 4, line 1: "cries" for "sobs"
Verse 4, line 3: "For" for "Oh!"
