It's been a big 2012 in the MacFarlane family.
 
Obviously, Seth had a big screen hit and was recently announced as the host of next spring's Oscars.
 
Sis Rachael, meanwhile, has continued with her vocal work as Hayley on "American Dad," but on September 25, she also released her first album, a collection of standards, plus rearranged '60s and '70s classics. Several tracks from the album were heard on last Sunday's "American Dad" premiere.
 
In this interview, MacFarlane discusses the style and inspiration for "Hayley Sings," as well as upcoming developments on "American Dad." 
 
"American Dad," of course, airs on Sunday nights at 9:30 on FOX.
