I think 'Horse To Water' was only ever intended for the Jools Holland album and not for any solo release by George. There is a video - or promo film clip - for the song (in black and white I think) which shows George and Jools Holland in a studio during the recording.
Talking of 'Brainwashed', I'm not sure if it's just me, but the vocals seems too forward in the mix. I suppose I'm used to George's voice being further back in the overall sound.
