Been trying to find the tracks by a guy with the stage name of Broadcaster who did some brilliant mixes of techno with samples of the Radio Ballads but can't track them down.

Of course Chumbawamba are a great example of a mix of more popular music and folk. Their Readymades CD that used samples of folk singers remains one of my favourites. Of course Biff Whalley of the band is also a superb song writer himself
