Randy Jackson and Ryan Seacrest Join Steven Tyler and Aerosmith for Live Jam [Video]

Thursday night in Oklahoma City, Steven Tyler enticed his pals Randy Jackson and Ryan Seacrest to hop on stage for a little jam session.

The band was playing a concert at Chesapeake Energy Arena when Tyler announced to the crowd, "Ryan Seacrest is in the house!"

The reason Seacrest and Jackson were hanging around is because they were in town filiming segments for American Idol which debuts in January.

Randy Jackson jumped in to play bass for a cover of the Beatles' "Come Together." Of course, Jackson felt right at home handling the bass rifts because he gained rock credentials as a former member of Journey.

Ryan Seacrest merely "sang" a little bit of harmony with Steven Tyler.
