Mandy Moore Performs 'When I Wasn't Watching' on 'Tonight Show'... With No Crowd Watching

Mandy Moore performs on The Tonight Show Starring Jimmy Fallon in March 12, 2020.

Only Mandy Moore can deliver a moody midtempo performance of "When I Wasn't Watching" without an audience watching after The Tonight Show Starring Jimmy Fallon taped its first show without a live crowd on Thursday night (March 12) due to coronavirus concerns.

It's that kind of riveting spirit she's had since she was 15 years old, selling "Candy" cassingles while opening for *NSYNC's 1999 summer amphitheater tour, that still moves through the 35-year-old singer today.
