I can remember that about the time I started getting interested in music, which is now well over two decades ago, Sade was really big. Then she just disappeared. She is supposed to be a bit of a recluse, but that is a significant hiatus! Anyway, she is now back, producing a new album. And on it will be this cover of "Still In Love With You" (Thin Lizzy), which I think is just about as mellow as it gets.
Good choice for a cover. It has also been done by Gary Moore. Also pretty damn good.
