Here's one for my 1970's buddies - do you remember Bachmann-Turner Overdrive and their hit "You Ain't Seen Nothing Yet"? It was a No 1 hit in 1974 and I remember in the pre-MP3 days when I listened to David Hamilton on BBC Radio 1 in school that I hoped and prayed that he would play this song. As I didn't have the single or a record player (if you've no idea what I'm talking about, Google it!) I along with my entire generation, was totally dependant on radio playlists to hear our favourite songs.
"You Ain't Seen Nothing Yet" is a symbol of my generation - it was "our song". Nothing reminds me of the 1970s more than this - enjoy!
