Thank you everybody for your help.
Kooperman, "Anything goes" by Cole Porter seems almost the perfect song i am looking for. The lyrics of this song are exactly what i am looking for, especially "the world's gone mad" so thank you.
Redneck4sure, which album is The Drifters - The World is Changing from? I would like to check it out.
Also, i have heard that Zager & Evans song before - the year 2525 - its a very good song.
If anyone else knows any more songs about a changing/changed/different world then please feel free to reply.
