Here in Canada the CBC will air the Back in the US special at 8pm ET. That's great as there are many time zone feeds on satellite for this and the CBC tends to have less commercials. I also got a notice this morning that both my CD and DVD where shipped yesterday via CDNOW so stores are getting stocked.
