American Top 40 with Casey Kasem aired on radio from July 4, 1970 until August 6, 1988. This rebroadcast is one of many I have recorded from internet radio. A few are incomplete but most are not and I hope you enjoy these as much as I do.
In this broadcast:

Casey answers the question, "Who has spent the most consecutive weeks in the top 40?"
Since numbers 4 and 24 are the same song, Casey skips playing number 24.
Casey answers the question, "Which act in the rock era has had the most double-sided hits: that is, where both sides of a single 45 RPM made the charts?"
