Cheryl Crow with some band on Jay Leno

They did a cover of that 60’s song “Time”(?)a couple of weeks ago. But Cheryl Crow was just a backup singer. When they went to talk to Leno. The guy from the band took the seat next to Leno and Cheryl took the one next to the guy. The guy did all the talking. This must be a pretty big name band to put Cheryl Crow in the second seat. Who are they?
