Blimp Time Hop: Heavenly Grateful Dead At The CCCC In 1980 Grateful Dead returned to Maine for their second sold-out appearance at the Civic Center in Portland. The ‘circus’ came back to town on May 11, 1980. The photo above was taken by my good friend and longtime Blimpster, Randy Heath of Auburn. He has seen more concerts than most people that I know and many, many of them have been Dead shows. I believe the great shot that you see here, was taken at here in Portland. Not sure if it's from the concert that we are commemorating today, but it looks like it could be. Thank you, Randy. We will hopefully feature more of his treasured Maine concert photos here in the future.
