Brian Willaims was lined up to do Jay Leno's "10 @ 10" last night. The "Nightly News" anchor is reporting from Afghanistan this week and "because of late breaking news" could not join the show. Luckily, "Meet the Press" anchor David Gregory was able to step in.

Should be a no-brainer because the segment is called "10 @ 10," but in the clip above, scroll to about 30mins in for Gregory... We learned Eli Manning was one of the last autographs Gregory asked for (for his son), he can name six 80s bands in 15 seconds and he plays music to get pumped up for "Meet" on Sundays.
