Emerson, Lake & Palmer performed on this day in 1978 at the Expo Square Pavilion in Tulsa, Oklahoma.

This particular leg of ELP’s Works Tour, which would prove to be their final set of shows prior to the band’s dissolution before the end of the year, was beset by weather issues. By the time the band began to play the night of the Tulsa show, the temperature had fallen to 23 degrees Fahrenheit! Doubtless, for some, it would have been unpleasant to venture out in such cold conditions! (source)

No recording of the concert is known to exist.
The Expo Square Pavilion, the venue at which they performed, was put upon land which had already been used for the Tulsa County Free Fair. It was built in 1931 and is known for its PWA Art Deco style which was popular at the time. It seats 6,311.

The venue is still in operation to this day, according to its website.
