IMHO, although I would not sing "This Land" as it sounds too American for my taste, if it is to be done it should be done as it was written, and it is a useful and international song about the theft of land by capitalism.

There are not enough songs about the land grab in England that was effected by the Inclosure Acts. although there is a nice short poem

"Tis bad enough in man or woman
To steal a goose from off the common
But surely he's without excuse
Who steals the common from the goose".

One of Bishop Gundulf's Morris's care in the community candidates sings "Drunken Sailor" (his repertoire is about 3 songs) and it's one of the things that has put me off it.

Time will restore most of the "sung to death" songs. Once upon a time "Dives and Lazarus" was sung (usually badly) to death but now it is a comparative rarity, and worth doing, particularly if well accompanied.
