It looks like Larry David’s comedy feature set up to debut on HBO finally has a name: Clear History.  More important than that oddly ambiguous title is the all-star cast that David and director Greg Mottola (Superbad) have lined up.  We previously reported that Jon Hamm (Mad Men) and Michael Keaton (Batman) were attached to star, but a slew of others have joined the production.  Clear History will also feature Kate Hudson, Bill Hader, Amy Ryan, Eva Mendes, JB Smoove, Danny McBride and Phillip Michael Hall.  Hit the jump for more on Clear History.

The cast and crew of Mad Men recorded a sing-a-long to the song ‘Bye Bye Birdie’ from the 60′s musical of the same name for showrunner Matthew Weiner.  It’s also worth noting in the episode Love Among the Ruins in Season 3, the agency was tasked with repurposing the same song for a jingle for a diet soda for women.  I’ll guess the video was recorded at the same time. Personally, I love seeing John Hamm being silly alongside January Jones.

Hit the jump to see the video, and make sure to watch after the song for all the bloopers.  Mad Men returns with new episodes this summer.
