There's no YouTube footage, at least not yet, but Hans Rotenberry stated that the Scott Ballew tribute gig would be The Shazam's final show. Former bassist Mick Wilson filled in on drums as the spirit of Scott looked on (projected behind the stage):

There were no holograms, just genuine love and respect.
Hans said that does intend to finish The Shazam's next (also final?) album,
the long-awaited Doomsday Hotel.
