Repeats of the show have aired since Thursday. Colbert’s mother died June 12 and, according to a tweet sent out by someone close to the show, Thursday’s new episode was canceled at the last minute.
New episodes originally were scheduled for Monday and Tuesday nights but later replaced with repeats.
However, tonight’s new episode, with guest The Postal Service, and tomorrow night’s show, featuring Joss Whedon, are advertised in TV listings.
Colbert canceled shows in February 2012 to take care of his mother, who reportedly was ill.
When he returned, he offered a series of joking explanations for his absence before giving his mother a brief shout-out.
