performances of the week

The Nard Dog, Bob Dylan, Betty White and More

What were the great performances of the last seven days of TV? From a haunting reimagining of a classic song to a ringing tackle of a classic TV star, the top five moments are all here in Vulture’s new video feature, “Performances of the Week.â€

In this installment:

Bob Dylan at PBS’s civil-rights commemorative concert, singing a spooky, piano-driven version of “The Times They Are A-Changing†in the White House itself.

The Office’s Ed Helms as Andy, delivering a company-wide e-mail via extremely awkward speech.

Saturday Night Live’s Fred Armisen leading a reunion of his eighties hard-core band at his daughter’s wedding reception. “You hear that, Alexander Haig?!â€

Betty White playing pickup football in the awesome Snickers Super Bowl ad that affirmed her revival. Next stop, SNL — if Facebook has anything to do with it.

And American Idol contestant Andrew Garcia turning “Straight Up†into a folk-pop jam. It’s a shame Paula wasn’t there to hear it.
