Family Guycreator Seth MacFarlane is adding another gig to his resume – a Saturday Night Live host. The man behind the hit summer movie Ted will host the 38th season premiere of the NBC sketch show on September 15. But despite his music credentials as a Grammy nominee, MacFarlane will leave the musical guest duties to Frank Ocean. Joseph Gordon-Levitt returns on September 22 for his second time as host with musical guest Mumford & Sons. Daniel Craig will host on Oct. 6 with musical guest Muse.
