[EX Q]: It is extremely rare to see so many world famous super artists performing together in the same concert doing some of their greatest hits - Elton John, Sting, Mark Knofler, Carl Perkin, Eric Clapton, Paul McCartney, Phil Colins etc. You must own this DVD before it is out of stock. I would have given it 5 stars should the audio recording be slightly better. Go and buy this one with confidence. I am sure you will not regret.
[EX A]: Positive

[EX Q]: As a student of jiujitsu i understood alot of the moves but i found that without previous knowledge these pictures and instructions were difficult to understand. I feel there is alot of good information but not worth buying.
[EX A]: Negative

[EX Q]: bryan wilson is da bomb! I am a singer myself and i know good talent when i hear it. and when he sang "His Eye is on the Sparrow", it blow me away! He is phenomenal and I love to hear him sing because he feels what he is singing about and what singing really is--the anointing you put into it, not the show so many people try to put on. I wish you much success in the future to come. Maybe I'll get to sing with you when I come out. May God forever bless you in your music ministry! Much love, Your sister in Christ, Connie
