This is wrong on at least two counts. I've been right through the MacColl/Seeger record collection and there are no copies of The Folksongs of Britain in there.

Likewise, I doubt if Bert ever drew on them for any of the songs they sang.

Both singers in fact had easy access to most of the original recordings and both made their own tape copies, so neither would have needed to draw on the LPs.

As for providing singing styles, can anyone think of a single traditional singer from anywhere within Britain or Ireland who sounded remotely like they might have been a model for either MacColl or Lloyd? I certainly can't.
