I can't offer a lot of information about this track or group (I don't know the year, composer or even where the group comes from) and this recommendation is also a request for more information if anyone has some. This track is a fantastic soul track that gets me everytime. I can't tire of it. It's from a compilation on Fat City Records and the sleevenotes offer little info. I don't believe this "Sounds of Joy" is the same "Sounds of Joy" that have an album with Wayne McGhie (recently re-issued). From the samples I've heard of Wayne McGhie & The Sounds of Joy, the sound is quite different. However, that is just a guess.
I hope you enjoy the quick sample.

Edit: thanks to Musical Taste, I have found a link which discusses each track individually, and it appears that the CD has incorrectly attributed this song to The Sounds of Joy when it should have been credited to The Shades of Joy (http://www.b-music.co.uk/finders_keepers.html).
