I was considering buying these, reprinted by Faber:

But I was wondering how different the songs' lyrics actually are? Is it literally a case of a word or a line here and there? There aren't any songs in these books that I don't already have in printed form somewhere - how revelatory are James Reeves' restored versions?

Can anyone tell me what Reeves' actually did to 'restore' the songs? Where did he source the original censored words? Printed broadsides? The original unedited notes of the song collectors?

Thanks all.
