The first is at the Prince's Trust Concert in 1986. You can see him at 2:00 into

Then there's the guy at 1:27 and 4:11 on

The last is
http://www.youtube.com/watch?v=G1lNMBsNEw8 . You can barely see him behind Sting at 4:22. At 6:20 there's a shot over his shoulder. The bass on this song is great and that's all they show of the guy. The tambourine player gets more love from the camera. Granted, it's Ray Cooper, but they may as well have put a ninja suit on the bass player, they hide him so well.
Thanks
