The band just announced the theme for this year's Mule-O-Ween, sharing artwork inspired by the Aerosmith logo, along with an Instagram post that drops several references to Aerosmith songs.
The inspiration for this year's theme may have come from Gov't Mule's current tour, dubbed the Back in the Saddle tour. "Back in the Saddle" is a track on Aerosmith's fourth studio album, 1976's Rocks.
The Back in the Saddle tour hits Toronto on Wednesday. A complete list of dates can be found at Mule.net.
