Slim Harpo (real name - James Moore) is a deceased harmonica player/vocalist/guitarist. Slim made this record for Excello in Nashville in late 1969, then returned home to Louisianna where he died of a massive heart attack in January 1970 at the age of 46. Slim Harpo invented the whole "swamp blues" thing and was a hero to many rockers (including Mick Jagger). His tunes ("I'm a King Bee," " Got Love if you Want It," etc.) have been covered by many. It is a hoot to hear him covering a tune by a country artist - Johnny Cash. Here is a link that will take you (eventually) to an MP3 of the record).
