at the moment we lowercase attributes when displaying them which (wrongly) turns things like "Hawaiian guitar" and "Hammond organ" into "hawaiian guitar" and "hammond organ", instead we should just store them capitalised normally and then display them without changing the capitalisation.
the capitalisation would need fixing for the current ones which are unnecessarily capitalised, but I can do that
I've pushed out a review that stops calling lc on relationships. In that branch, there is an SQL update file that lower cases all attributes, so if you could have a look and see which need fixing, then hand the branch back to me, that would be great.
