John Mayer Shreds The Blues At Dead & Company Rehearsal With Sammy Hagar [Watch]

Just days before Monday’s free show in San Francisco, Dead & Company held a band rehearsal that lured in some vocal assistance from Sammy Hagar. The Red Rocker joined in for a nice little blues jam on Thursday afternoon alongside John Mayer, Oteil Burbridge, and Bill Kreutzmann. There are no details as to whether this means that the band will be welcoming their first ever special guest to the stage, or if this meeting was just for fun. While probably the latter, this is still a fun teaser as we gear up for a tour-filled summer with Dead & Co.

Here is a video posted by Oteil Burbridge. Enjoy!
