There was an exhibit on the second floor which showed how radios and record players evolved over the years. It started with the Thomas Edision era and proceeded through vinyl records, 8-track tapes, cassettes, CDs, MP3 players and satellite radio. Downstairs there was an interactive exhibit where on a computer screen you can touch a decade, city and find the predominant radio personalities and hear a short aircheck. So for NYC in the 1960s there was Cousin Bruce Morrow, Harry Harrison, Ron Lundy, Scott Muni and Herb Oscar Anderson among others. The late Jackson Armstrong was listed for Cleveland although he worked in many radio stations in various cities. This will be my last entry about our trip to the Rock and Roll Hall of Fame.
