I was very curious about it. I only know him due to his food stuff on the TV but I found this fascinating. I think it was good that he decided his friends should come to as I am sure he enjoyed it more.
It was fascinating that actually some of the things he does are considered Haram. I have forgotten the name of the thing it is called when you go to Mecca and do the ritual(s) , not the Hajj, the other thing, and wonder if you then have to give up things you had been doing - in his case, designer gear, talking to girls and a bit of alcohol and singing!
