It is Jimmy London, and the track is called "A Little Love", and you can download it from http://www.btinternet.com/~ranksreggaerevival/mp3_
page.htm
Just copy and paste this address into your browser bar, and press enter. (It's near the bottom of the page) right click, and save as, then de-compress/convert it into a full length MP3/WAV, with a program like dbpoweramp. www.dbpoweramp.com.
Hope this helps. :)
Thanks fellers. I didn't think I was ever going to find out. The new Trojan 3 CD box set is excellent, by the way, has pretty much everythig on there (apart from this track of course).
