Emerson, Lake & Palmer performed on this day in 1971 at Green’s Playhouse in Glasgow, Scotland.

ELP were on the first leg of their Tarkus Tour, which would take them on a journey spanning both sides of the Atlantic. By the time they played their last concert (incidentally, also at Green’s Playhouse) in the middle of December, they had done two legs in the United Kingdom, two legs in the United States, and one leg in Western Europe.
There is no known recording of this concert.
I talk more about Green’s Playhouse, where the band performed, here.
