AT 40 1971

Show Date	Comment, if any	Length (min)	Location
Note that, from the beginning of AT 40 in July 1970 through the May 1, 1971 show, a chart of a particular date was actually broadcast one week ahead. For example, the show broadcast on October 3, 1970 actually was based on the chart dated October 10, 1970. I've noted below air dates and chart dates for shows through May 1, 1971. Casey did not begin mentioning at the end of the show the date of the Billboard chart just counted down until later in the '70s. The first AT 40 special was broadcast the week of May 8, 1971, and after this, the show date and chart date were synchronized.

7/3/71	AT 40's first anniversary. No special show is done, but Casey does mention the anniversary both at the beginning and at the end of the program. He also mentions that AT 40 went from being heard on seven stations on its debut in July 1970 to 118 stations worldwide by the date of this program.	155	CD802-803/HD

11/6/71	Casey Kasem is off this week shooting a movie, so AT 40 writer/producer Don Bustany (whom Casey credited every week and whom it's nice to finally hear the voice of) introduces the guest host, the "Hullabaloo-er" from LA's KGBS, Dave Hull.	143	1991-1992/HD
