'We singers make bold' appears in The Joy of Christmas, Worrall Male Voice Choir, and the note says simply: 'Closely associated with the Mount family. Different versions widespread throughout the country.'
It is also on the Leader recording A People's Carol, which has a cover photo of the Mount family carol party. The specific note here says:
'This carol is found in other parts of the country and is quite distinct from the 'figgy pudding' or the 'pocketful of money' versions. It has always been a great favourite locally for it occurs in many of the older manuscript books and is frequently mentioned in the newspaper accounts.'
There is also mention of 'the elaborate five volumes that had once belonged to the Mount family of Worrall'.
I also remember English Tapestry singing it, albeit briefly.
