The Indiana Fairgrounds Coliseum Eagles concert with Yes and Gentle Giant was on September 20, 1972. It was in Indianapolis at the State Fair Coliseum building located on the fairgrounds property. It is now called the Indiana Farmers Coliseum. Gentle Giant opened the show first, followed by the Eagles, then Yes as the headliner. This concert was part of the Eagles’ first tour and was one of many that the Eagles opened for Yes. Another show they opened for Yes was at the Carolina Coliseum in Columbia, SC a few days later on October 2, 1972.

Coliseum Yes/Eagles concert tickets were $5.50, $4.50, and $3.50

“The Eagles came on strong, although not quite screaming, for their set which proved their versatility both vocally and instrumentally in performing out-of-the-rut tunes of differing tempos and moods with musical acumen and sensitivity.”
