Each weekend, we rebroadcast the original versions of Casey Kasem's American Top 40. It's really fun to listen to those shows again. It's a chance to hear all those great hits in the context of the Billboard top 40 Charts and find out what else was floating around on the music charts back when all these classic hits were brand  new songs.

Some of the songs we hear each weekend never climbed high enough on the charts to get played in today's radio market. The inclusion of those songs that didn't quite make it is also part of the charm on the show. More than once I've been listening and thought to myself, 'I haven't heard that song since it was new'!

Here's a sneak peek at this weekend's Casey Kasem's American Top 40, the 70s

This weekend, we'll be rebroadcasting Casey' show from March 9, 1974.

On this weekend's show you'' hear a great tune from Gladys Knight and the Pips at #32. It's the great Jim Weatherly penned hit, 'Best Thing that Ever Happened to Me.' Weatherly also wrote 'Midnight Train to Georgia.'

Elton John's 'Bennie and the Jets' was at # 23

Coming in at #21 is one of the most unusual hits of the 70s, it's Blue Swede and the 'ooga chocka' version of the B.J. Thomas hit, 'Hooked on a Feeling.'

Paul McCartney was at #14 with 'Jet" and John Denver was sitting at #10 with 'Sunshine on My Shoulders.'

Those are just a few of the songs you'll hear on this weekend's show as Casey counts 'em down to #1. What was number one that week? Tune in Saturday and Sunday morning at 9 a.m. and find out!
