Well you could always buy the recently re-released CD of the original Radio Ballads (on the Topic label in the UK); when I posted on this to r.m.f. someone added a US source which a search of DejaNews would show up . . Sorry I can't do that myself but DejaNews seems good at crashing Netscape ATM. The CDs, unlike the earlier vinyl releases on Argo, are of the complete broadcasts.That being said, I have a sneaking feeling it was more common for extra verses to find their way into versions outside the Radio Ballads (where time was limited) . .
Also - can anyone recall the (UK) South Bank concert where June Tabor paired one of the "Travelling People" songs with "All our trades are gone"? If so, can they remind me which song it was. Unfortunately the CD which came out not a lot later only had "Trades. ." on it.
