Muhammad Ali was planning to stage a charity concert with different music groups that was popular at the time. Nothing became of it as far as I know. Anyway the group and Joseph are in this footage. They don't say anything, except for a couple of lines from Mike & Jackie.
There you go Jermaine, Tito, Marlon and Jackie ! Thats why you have to get your butts into the studio and sort some new tunes out! Im positive you *still have it* you just have to make time and work at it! Perfection does not get given, its worked for!!
