r4 producers must know what their audience likes.
I enjoyed the 'music' bits, MC etc.
I suppose the Claire Jones/Chris Marshall, Sally/Mike Masheder bits were the 'soul' of the programme title.

Too much wind noise for a radio prog but there is a better H&P version on YTube Hayward & Parsons -Scarborough Fair.

Their FB page is Hayward & Parsons FaceBook with links to other songs.

I've been enjoying the early one by Audrey Coppard (pos' only a spotify link)Audrey Coppard -Scarborough Fair.

and the slightly different melody of Gordon Heath/Lee Payant -Scarborough Fair (pos' only a spotify link) though the style is somewhat odd!
