That sounds good. As I said before, there are various ways to chord many songs, and the one I use is a little arty-farty with all those minor chords. But yours works perfectly well, so go for it. Great song and enjoy it. Did you know that it's a sort of parody, as it's based on the song 'The Roast Beef of Old England', at least tune-wise, so in the old days people would have spotted that and realised the irony of singing a song about poverty to a tune associated with feasting. Not a lot of people know that!
