There are any number of threads concerning the tune used by AG, and nearly all of them remark that the tune was originally "New Britain". But nowhere have I found the words that were sung to the tune before AG became attached and superseded them. A google search brings up 95 million results, but all the links I've followed merely mention New Britain as the tune to AG.

So, does anyone know the original words to New Britain, or indeed any set of words to the tune that can be dated to before its adoption by AG? Wikipedia claims one William Walker made the link in 1835.

Note: I've deliberately avoided spelling out A m z a i g n g a r c e in a form that would be recognised by searches- it's New Britain I'm interested in, the hymn itself has been discussed to the point where nobody is likely to add anything new or interesting.
