I caught a part of a show at my job in Connecticut yesterday. I think the show in the early evening (ET) said "for the week ending August 14, 1982." Around 10 PM (ET), they were wrapping up a show from the latter part of 1986. "When I Think Of You" from Janet Jackson moved from #7 to #3 and "was #1 on the Dance Chart". There's one other distinct part of the show I want to hear them play. Once each hour, Casey would proclaim "American Top 40 is heard in the 50 states and around the world on great radio stations like...". That would be sweet! I've still got one or two of those on tape from winter and summer of 1988 (just before he left and Shadoe Stevens took over).
Speaking of "AT40", is the version done by Ryan Seacrest still around? Also, does that show use info from Billboard Magazine? If it doesn't, then I won't listen.
