The Folk Singers Wordbook suggests the following:

There (C) was a (Dm) Lord in (C) London (Dm) town,
He (F) courted a (G7) lady (C) gay,
And (F) all that he (G7) courted this (C) lady (Am) for
Was to (Dm) take her (C) sweet life a(Dm)way.

Hope this helps. I don't know the tune, so I can't vouch for it.
