There has been a change in the lineup. Comedian and former “Tonight Show” host Jay Leno is replacing Aretha Franklin at the opening night of the Chautauqua Institution’s new amphitheater. Leno replaced Franklin after she canceled her appearance due to illness. Anyone who bought tickets for the Aretha Franklin concert will have their tickets honored for the Leno show. If you wish to get a refund due to the change of performers, you may call the Chautauqua Institution.
