Sheryl Crow is still going strong.

The nine-time Grammy award winner stopped by Late Night With Seth Meyers to perform her new song, "Roller Skate" last night (September 7). It's chock full of the soulful rock we've grown accustomed to hearing from the acclaimed singer.

Plus, the NFL season officially kicked off, so The Tonight Show got into the spirit of things by enlisting Reese Witherspoon to play a game of Cooler Heads, in which she and host Jimmy Fallon had to answer football trivia questions. If they got any wrong, they'd have a cooler full of some "mystery substance" dumped over their heads. If they were right, the other person would get doused. As you might imagine, hilarity ensued.

Meanwhile, Jimmy Kimmel Live! had some fun discussing new Bachelor star Arie Luyendyk, Jr., poking fun at his career of choice and his name.

On The Late Show, Bernie Sanders stopped by for a compelling interview with Stephen Colbert where he spoke out on Hillary Clinton's new memoir.

On The Late Late Show, Dana Carvey and Lake Bell used their powers of impersonation to act out what was being said in Instagram photos with some very famous people.
