OK, it took me less time than I thought.
Here it goes: http://ewan-maccoll.info/JohnRossList.aspx

I've made no changes to the original file, so it looks the same as it was, except for one thing: I've added links to detailed information for each album. (Not all of them - some releases are absent on my site - some compilations and 78rpms). So John Ross' discography is now "clickable" :-)
