Tonight’s first show of 2013 (HBO, 10 p.m. ET) will include a flashback and update of Andrea Kremer’s 2011 story on the Harbaugh family.

Said Kremer in an email:

“The inundation of Harbaugh-dom is upon us. The original story was shot on vacation at Gettysburg with the boys and their parents and is a tremendous window into their relationship, with great stories and access.

“With the advantage of time passing, we also went back to the original tapes and added in related material.  There’s a new and funny section on “who’s got it better than us” which Jim embraces but John says is too corny.

“And, there’s a cool story that Jack tells about Jim and the drafting of Kaepernick (video below).”
