When Jimmy Fallon had Randy Jackson on 'Late Night' (Weeknights, 12:37AM ET on NBC), it was all fine and dandy to talk about 'American Idol' and all of that. But what would be really fun would be to jam with Jackson on a Journey track.

To make it more memorable, Jackson invited a friend along to help Fallon with the singing. And it's someone his 'Idol' fans would recognize right away.

Fresh off his surprise elimination from the singing competition, James Durbin lit up the 'Late Night' stage and proved he doesn't need any title from a reality show to prove that he has amazing chops.

While their harmonies may have been a little strange, it was a lot of fun seeing Jackson playing bass on a song from his old band's catalog, and Fallon and Durbin were clearly having a lot of fun sharing the vocals. It was certainly a fun and memorable moment.
