This entry has me concerned... 1971 – Fleetwood Mac and Deep Purple play Madison Square Garden’s Felt Forum theater.
I can verify that Fleetwood Mac played at the Felt Forum on this day, and I can verify that Deep Purple played at the Felt Forum on this day, but I can't verify that they played there together, and I don't believe there were two separate shows. The two bands have toured together back in the early '70s, so it's not unusual...
