Ruddy Thomas is a name I usually associate with lovers tunes: he did a nice version of 'Every Day Is A Holiday' for Joe Gibbs, for example, and 'Time To Leave Daddy' is simply magnificent. It's not so often that you hear him singing a serious roots tune, but far stranger things have happened.
'Go Home Son' is one of his best: it's the original vocal to Dillinger's 'Five Man Army' and although it has a more commercial sound it definitely holds its own against the other cuts. There's another vocal by Echo Minott: he versions 'Woman In Love' by Barbra Streisand, which I've always enjoyed in spite of myself!
All the clips of the Barbra Streisand version in youtube are restricted use, so I can't embed them. This one is Bronislaw Komarowski, the late speaker of the Polish parliament.
