I'm overwhelmed already! It may take more time and space than I'd expected. I started on my own versions last night and found the table format gets unwieldy very quickly. Any better ideas? A permathread with one post allocated to each ballad, for instance?

Two more points: I was thinking of recordings, including different versions, not of versions on paper. However, it may be worth adding the info whether or not a particular version can be found in Child.

I must admit to a limited music-literacy, so I'm not that much concerned with different tunes. However, from the last few posts above it looks like adding whether or not a particular tune is traditional (i.e. found in Bronson) or a later addition may also be worthwhile. (I'm thinking of e.g. the modern tune for 'Twa Corbies', or Pentangle's use of the trad. tune of Child #1 for 'Cruel Sister'.)

Did I mention I'm already more than fully employed? :-)
