One odd side effect for a lot of people who were kids in the 70s, is that between Happy Days and Sha Na Na, you have as much familiarity with 50s tunes as the stuff that was new then. Granted, if you had to choose between Anson Williams crucifying a Doo Wop classic or Frank Marino and Mahogany Rush, nobody wins. But I still dig Bowser, Jocko, Lenny, etc.
