Thanks to Lois from the message board for letting me know about this :) She says..
I wrote to the Regis show this afternoon asking about Jason’s appearance on
the show September 4. Unfortunately, I received the following response.
Thanks for taking the time to write to us, and for
watching and supporting LIVE.
It was scheduled to be on Sept.4th but it will no
longer air on that day and we have no plans to
when we’ll air it as of yet. Please keep chekcing
back with our website under “upcoming Guests.”
