My wife just emailed this tune to me, telling me that she wishes I could sing like this (so do I). It's a beautiful song, but I think the conguero is also playing a very instructive role for us on the forum as well. He's pulling triple duty by playing a conga, bells, and bongo setup (and clave with his foot I believe). This is a "how-to" video for percussionists in this kind of setting who wonder which parts to play and which to omit. Of course it's a very personal preference, but I think this is just perfectly tasteful playing... Plus, I dug up the lyrics online, and maybe will try to surprise my lady one of these days.
Here's the tune...
