Music Track - Traffic

When I first visited the USA in 1969 - I had my 30th birthday in New York, it was quite a blast - this was very popular at the time http://www.youtube.com/watch?v=y9t_8oth7LA  I was roaming around the U-Tube site and found it.  I don't think I've heard it for over 40 years.  I might leave it another 40! It's pretty typical of the music that was played in the peak of flower power.
