Sax and flute player Gerry Niewood of Rochester, N.Y., and guitarist Coleman Mellett of Maryland were among the fatalities of Flight 3407.

“I’m in shock over the horrible, heartbreaking tragedy of the crash of Flight 3407, which took the lives of my dear friends and band members,” Mangione said in a statement. “I am grieving and praying with their families and friends.”

Mangione and his band were to play with the Buffalo Philharmonic Orchestra Friday night. That engagement has been postponed.
