You don't have to wait to ask a ninja how the show was: YouTube.com is live streaming its first global concert event starting at 8 p.m. ET Saturday at youtube.com/live.

The two-hour event, streaming from San Francisco, will bring together artists including Katy Perry, Akon, Will.i.am and Internet stars such as Esmée Denters, Michael Buckley ("What the Buck") and "Chocolate Rain" singer Tay Zonday, who will play announcer.
