Deep Purple performed on this day at the Electric Circus in New York City. It was their sixth consecutive night at this location.

As with all previous nights at this location, Purple played two shows, one at 9 PM and one at 11 PM.
The Electric Circus was the final venue at which Purple played on their first US tour. Mark I was actually back in the United States in the spring, an incredible feat given this lineup fell apart only six months after the first tour concluded. Truly, they were a hardworking group!
No recording of either concert is known to exist.
I talk about the venue a bit more in this post.
