Legendary musician and longtime Democratic Party supporter James Taylor told his fans he was “sorry to disappoint” them on the opening night of the Democratic National Convention, in which his performance was cut due to significant programming delays.

“It was exciting to see and hear so many of the speakers at the opening night of the Democratic convention here in Chicago. And we had a great rehearsal with @RickeyMinor and terrific singers @KenyaHathaway and Mathew Johnson before the event,” Taylor wrote on Instagram.
