The world-premiere event will celebrate the late award-winning composer, whose numerous accomplishments included the Tony and Pulitzer Prize-winning musical A Chorus Line.
Produced by writer and pianist Kevin Cole, the concert promises "an insider's view into Hamlisch’s life through song, private family videos and personal memories." It will mark the occasion of what would have been Hamlisch's 70th birthday.
James (Sweet Smell of Success) and Friedman (Ragtime), will join Cole, Grammy Award winner Sylvia McNair and conductor J. Ernest Green.
"The reason I am doing the world premiere with the Pittsburgh Symphony Orchestra is because not only is it one of the greatest symphonies on the planet, but a huge part of Marvin's heart remains in Pittsburgh," Cole said in a statement.
