Only qualified to give MHO, but I always thought of Omar as AJ, and was excited 
to finally see him get to the states two years ago I guess it was.  Saw  him 
play at Bimbo's here is SF and was disappointed by his, shall we say attitude 
after the show.  He was way into himself which I suppose annoyed me, since we 
we were so psyched for him, but is irrelevant I suppose.  As my fading memory 
recalls, I was also somewhat disappointed by the performance, but that may be 
tainted! 
Anyway, my friends and I always classified Omar as AJ.  Interested to hear if 
others disagree.
