Despite the objections, within months gospel blues had proven to be established in Chicago's black churches. In 1933, Dorsey directed a 600-person chorus at the second meeting of the NCGCC, now boasting 3,500 members in 24 states. Black gospel choirs were asked to perform at several white churches in Chicago. And Dorsey's own Pilgrim Baptist Church choir performed at the 1933 World's Fair.
