The guy who invented the Fifties works right down the hall from me. Apparently, nostalgia toward the Fifties as a Happy Time (along with the invention of the Greaser as the quintessential Fifties rebel) can be dated to 1969 with the advent of Sha Na Na. And who invented Sha Na Na? The guy who works down the hall from me. Small world. I’ve never met him, by the way. I’ve never spoken with most of the people who work down the hall from me.
