Good Morning America featured Jeffrey Biegel with the final section of Rhapsody in Blue with some original cadenzas by George Gershwin, prior to his performance with orchestra at Avery Fisher Hall the same evening.
Playing 2 versions of a piece in 1 day, 1st a solo piano arrangement on an out of tune piano, than an orchestra arrangement, sounds real tough. At least live TV doesn't feel as permanent as studio performing.
