Here’s another gem of an SNL vintage rerun: Tom Hanks is the host of this show, guest hosting in 1990, just two years after making the shift from Bosom Buddies to movie star as the big-screen star of Big. The young kid showed such promise. Whatever happened to him?  The musical guest is Aerosmith – so watch this 1990 edited-down installment and realize that decades in Steven Tyler’s future is a gig as judge on American Idol.
