That makes me feel very old; 30 years ago and I remember it so well. Bob Marley was not the first reggae artist that I listened to, nor is he the one I love the most (that's Jimmy Cliff) but he is the one that I can happily talk to with people in London, Amsterdam, Paris, the Caribbean, the far East, Mauritius....
So here's a few of my favourites...
"Redemption Song"
A great acoustic version of which can be heard here.
"Stir It Up"
If you don't know the songs of Bob Marley then go to You Tube and take a listn. If you do know them then take a look around anyway.
