VIDEO: Family Guy creator sings karaoke as the show’s cast on Graham Norton

’Family Guy’ and ’Ted’ creator Seth MacFarlane appeared on the Graham Norton Show to promote his new movie Ted 2 - alongside singer Cyndi Lauper.

MacFarlane voices a whole host of characters on 'Family Guy', including Peter Griffin, Stewie, Brian, and Quagmire - and what better use for that talent than a karaoke extravaganza of Cyndi Lauper songs?

A little prodding from Norton was all that was required for MacFarlane to jump right in without rehearsal. Impressive stuff.
