American Top 40 The Seventies Sunday May 26th – May 25th 1974
Casey counted down the 40 biggest hits off of Billboard’s Hot 100 Singles chart. Originally a 3 hour program, AT40 expanded to the now familiar 4 hour length in 1978. Besides the top 40, AT40 played Long Distance Dedications and extras. The first Long Distance Dedication, “Desiree” by Neil Diamond, aired in 1978. Fans could also write in questions and have the AT40 staff answer them, sometimes on the air. 1974 would be the year that Steely Dan had the biggest hit of their career called Rikki Don’t Lose That Number. Here is the video.
