""all" recordings of all of the Child ballads."
Good luck with 'The Outlaw Murray
MacColl and Seeger's 'Long Harvest' (12 vol) and 'Blood and Roses' (5 vol) which set out compare the British and American ballad traditions are my particular favoorites, followed by 'The Muckle Sangs' on the School of Scottish Studies series
Bronson described the Lloyd/MacColl Riverside series as "the most important addition to our knowledge of the traditional song tradition since Sharp"

I have now managed to put together nearly 100 of the Child ballads which became part of the Irish singing tradition, with at least three times that many versions
Ireland probably had more ballads in is oral tradition than England
