WASHINGTON — Aerosmith fans who went to the group’s concert in Mansfield, Massachusetts got quite a surprise this week. Johnny Depp joined the rockers on stage.

A fan took a video of Depp playing “Train Kept A’Rollin” with Aerosmith.

It was the concert’s final number, and Depp cranked out a guitar solo during the performance.
