Allways must thank you for posting, HOWEVER:
THIS POST IS INCORRECT!
Pink Floyd did not play in Boston on March 13th, 1973; they and their equipment were in transit from Maple Leaf Gardens in Toronto, Canada after playing there March 11th, 1973.
The WORST ABOUT THIS RECORDING IS THAT IT IS AT A MEASLY 64 kbps, which is sort of akin to listening to music through a 100 foot plastic sewer pipe.

It is a great disservice to take a great recording and degrade it.
