Closing out this year's CES keynote, Microsoft's Robbie Bach invited Guitar Hero champion Kelly "TipperQueen" Law-Yone on stage to play Guns n' Roses' "Welcome to the Jungle" on Guitar Hero 3. Not willing to be outdone, keynote speaker Bill Gates brings out Slash - of Guns n' Roses fame - to play "Welcome to the Jungle" on a real guitar.

Instead, we'll just spend our time wishing for this performance - and The Office parody from earlier in the keynote - show up as online video soon.
