Meant to mention yesterday: Casey's '80s went to 1985. Since I was listening to AT40 ardently at this period, nothing was NTM. We missed by one week a near-forgotten (Ray Parker Jr.'s "Girls Are More Fun" dropped out) but the only tune that seemed close to obscure was the Thompson Twins' "Lay Your Hands on Me."
I assume this week will take us to the late end of the '70s, giving me hope that the following week will be '72. If every oldies station in America doesn't take a Christmas hiatus, that is.
