A bit of a reverse jinx in 12/6/80. When Casey mentioned Rick Springfield in a list of Australian acts who had hit the top 40 (while introducing Air Supply) he probably had no idea that the former 1972 one-hit wonder would have a string of hits starting in 1981.
On AT40: The 80's 12/12/1987: Casey mentioned Billy Idol had hit #1 for the first time with "Mony Mony", but it would be 3 more years until Billy Idol would make the top 40 one more time with "Cradle of Love" (And during the Shadoe Stevens AT40 era).
On this week's 1973 show Casey said debuting Corazon was a hot record by a hot artist. It would climb to 37-39 the following week and was out of the top 40 the next.
The 12/22/1973 week Corazon fell out of the top 40 was the same week AT40 did the 1973 Christmas countdown shutting out El Chicano's and Ann Peebles' songs from being played on their only top 40 weeks!
On 12/12/87, Casey said of Jody Watley's "Don't You Want Me", "Lookin' as good as Looking For a New Love, which hit #2 back in May." But DYWM, at #9 that week, only peaked at #6. Jody did return to the #2 spot in 1989 with "Real Love", but never got a pop #1.
