I heard this on the radio at Subway the other day, I've always loved this song. The single is a little more silky, but I like the slight grit of this live performance. It's a little more sexy. Lord knows George Benson could hardly be more sexy!
Sometimes it pays to read the comments on Youtube - - "George Orlando" pointed out that the bass player is playing the tambourine with his foot at 2:29, and you can actually see it at 3:13.
